CVSS v3.1 |
| PJSIP is a free and open source multimedia communication library written in C. In 2.17 and earlier, the PJSIP AVI parser in pjmedia/src/pjmedia/avi_player.c uses an input-file video chunk length as the number of bytes copied into a frame buffer whose capacity is derived from the declared media dimensions. A crafted AVI file can therefore cause an attacker-controlled out-of-bounds write past the heap allocation when an application plays the file or pulls its frames. The existing size assertion does not protect production release builds, where assertions are disabled. Typical local playback can crash the process, while applications that accept untrusted AVI sources expose a stronger memory-corruption condition. No fixed version is available as of this review. |
| Dell OpenManage Server Administrator, versions prior to 11.1.0.3, contains an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Remote execution. |
| In the Linux kernel, the following vulnerability has been resolved:
net/sched: fq_codel: clamp default quantum and mtu
fq_codel_init() sets q->quantum = psched_mtu(qdisc_dev(sch)) without
clamping. A device with a huge MTU (e.g. dummy with max_mtu == 0
accepting MTU 2147483634) makes psched_mtu() return 0x80000000, which
overflows the signed flow->deficit to INT_MIN in fq_codel_dequeue(),
causing an infinite loop and soft lockup. Emulate fq_codel_change()
and constrain to [256, FQ_CODEL_QUANTUM_MAX].
The same unclamped psched_mtu() is assigned to q->cparams.mtu a bit
below, and fq_codel_change() never updates it. codel_should_drop()
tests "*backlog <= params->mtu"; with mtu == 0x80000000 (~2 GiB) and
the default 32 MiB memory_limit, the test is always true, so CoDel is
silently and completely disabled (no drops, no ECN). Declare a single
clamped mtu and assign both q->quantum and q->cparams.mtu from it,
which also removes the double psched_mtu() call.
Conditions to recreate the bug: a device whose MTU (plus
hard_header_len) wraps psched_mtu() into the sign bit (e.g. a dummy
device with max_mtu == 0 accepting MTU 2147483634). Requires
CAP_NET_ADMIN in a user namespace. |

net/sched: act_skbmod: fix length calculations and avoid invalid header warnings
syzbot reported a warning in skb_network_header_len() triggered
by tcf_skbmod_act():
!skb_transport_header_was_set(skb)
WARNING: CPU: 0 PID: 14949 at include/linux/skbuff.h:3243 skb_network_header_len include/linux/skbuff.h:3243 [inline]
WARNING: CPU: 0 PID: 14949 at net/sched/act_skbmod.c:55 tcf_skbmod_act+0xfe8/0x1810 net/sched/act_skbmod.c:55
There are a few issues in tcf_skbmod_act():
1. Calling skb_network_header_len() assumes skb->transport_header is set,
which is not guaranteed when tcf_skbmod_act() runs at TC ingress.
2. Unconditionally calling skb_mac_header_len() at the beginning of
tcf_skbmod_act() triggers a warning on L3 devices (e.g. TUN) where the
MAC header is unset, evaluating to an underflowed garbage length.
3. On TC ingress, skb->data points to the network header. Adding the MAC
header length to the IP header length causes skb_ensure_writable() to
request more bytes than the actual IP packet length, dropping valid
short packets (e.g. 28-byte UDP/IPv4 packets).
Fix these by:
- Using skb_network_offset(skb) + sizeof(struct iphdr/ipv6hdr) for
SKBMOD_F_ECN so that the required length is correctly calculated on
both ingress (offset == 0) and egress (offset == mac_len).
- Setting max_edit_len to ETH_HLEN for Ethernet header modifications
after validating ARPHRD_ETHER. |

net: sparx5: fix sleep in atomic context in MAC table access
sparx5_set_rx_mode() runs with netif_addr_lock_bh held and iterates
dev->mc via __dev_mc_sync(), which per address calls sparx5_mc_sync() /
sparx5_mc_unsync() -> sparx5_mact_learn() / sparx5_mact_forget(). These
take sparx5->lock, a mutex, and then poll the MAC access command
register with readx_poll_timeout(). A mutex may block, which is not
allowed from atomic context.
Convert the driver to the new .ndo_set_rx_mode_async callback introduced
in commit 3554b4345d85 ("net: introduce ndo_set_rx_mode_async and
netdev_rx_mode_work"). The async callback is invoked from process
context, so the mutex and sleeping completion poll can remain.

| adm-zip is a JavaScript library for creating and extracting ZIP archives in Node.js. Prior to 0.6.1, getData() in zipEntry.js trusts an entry's central-directory uncompressed size and allocates output memory before validating that value against the actual compressed data and decompression result. A small crafted ZIP can declare a multi-gigabyte uncompressed size, causing Buffer.alloc and decompression handling to commit excessive resident memory before CRC validation reports an error. Applications that read entries from untrusted archives can therefore be terminated by the operating system or suffer service-wide memory exhaustion. This issue is fixed in version 0.6.1. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: do not leak an hci_conn when a second LE connect is rejected
create_le_conn_complete() decides whether the failed connection is
still pending by comparing it against hci_lookup_le_connect(), which
returns the first LE connection in BT_CONNECT. That is the same
connection only while at most one is pending.
Two can be pending. Connections created on the passive scan path sit
in BT_CONNECT with HCI_CONN_SCANNING set and are invisible to
hci_lookup_le_connect() until hci_le_create_conn_sync() clears the
flag when their command is issued, so the -EBUSY guard in
hci_connect_le() does not prevent a second connection from being
queued while the first is still on the scan path. Whenever two
connections are in BT_CONNECT at once, the lookup may return one
connection while create_le_conn_complete() is reporting the failure
of the other; the early exit then drops the error and hci_conn_failed()
never runs on the connection that failed.
The controller also rejects a second HCI_OP_LE_CREATE_CONN issued
while another connection creation is still outstanding, per Core Spec
Vol 4, Part E. The spec calls for Command Disallowed there; the
bcm43438 observed here answers with an LMP/LL error code instead,
which bt_to_errno() maps to the -EPROTO (-71) in the log below.
The leaked connection stays in BT_CONNECT forever, and because
hci_connect_le() refuses to dial while hci_lookup_le_connect() finds
anything, every subsequent attempt to reach any peer fails with
-EBUSY and no command reaches the controller at all.
Seen on a bcm43438 with two BLE peers polled on the same interval
(state 5 is BT_CONNECT; both handles are UNSET ones, allocated from
the ida above HCI_CONN_HANDLE_MAX):
Bluetooth: hci1: Opcode 0x2013 failed: -71
# hcitool con
< LE 14:9C:EF:03:68:81 handle 3840 state 5 lm CENTRAL
< LE C4:D3:6A:8C:B5:38 handle 3841 state 5 lm CENTRAL
A btmon capture across the next ten minutes of connect attempts
contains no HCI_OP_LE_CREATE_CONN at all; outgoing LE connections
do not recover until the adapter is reset. With this change the same
scenario fails the rejected connection cleanly and further connects
to both peers go through.
Ask about the connection itself instead of about the device. |

vdpa/mlx5: fix wrong list iterated in add_direct_chain error path
In add_direct_chain(), newly allocated direct MR entries are added to
the local list 'tmp', which is spliced into mr->head only on success.
On the error path, the cleanup loop was incorrectly iterating over
mr->head instead of tmp.
Fix by iterating over 'tmp' in the err_alloc cleanup path. |
| In the Linux kernel, the following vulnerability has been resolved:
NFS: Return a delegation the client fails to record
When an NFS server grants a delegation in an OPEN reply,
nfs_inode_set_delegation() records it on the client. However, three
of its error flows return without sending DELEGRETURN.
A delegation can be relinquished only by DELEGRETURN (RFC 8881
Section 20.2.4), so dropping one silently leaves the server believing
the client still holds it. If the server happens to recall that
delegation, the client answers CB_RECALL with NFS4ERR_BADHANDLE
because it has no record of the stateid. The server revokes the
delegation and moves it onto its cl_revoked list, because the client
never sends the FREE_STATEID that would drain it. Every subsequent
SEQUENCE reply then carries SEQ4_STATUS_RECALLABLE_STATE_REVOKED,
and the client's state manager loops issuing TEST_STATEID across its
delegations without ever clearing the condition.
The window is easy to reach now that a server offers a write
delegation on any write OPEN: a delegation recalled for one opener
races a re-open that the server answers with a fresh write
delegation.
Instead of dropping it, hand the delegation back during these error
flows. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Check load-acquire src ptr type before the load
check_atomic_load() calls check_load_mem() before atomic_ptr_type_ok().
For a load-acquire that fetches into its own source register (dst_reg ==
src_reg), check_load_mem() overwrites src_reg's type with the type of the
loaded value, so the subsequent atomic_ptr_type_ok() no longer sees the
source pointer and fails to reject the disallowed types (ctx, pkt,
flow_keys, sock).
Since bpf_convert_ctx_accesses() does not rewrite atomic loads, the raw
access to the underlying kernel object is left in place. The destination
type is taken from the ctx access itself, so a load-acquire of the sk
field of struct __sk_buff for example leaves the register typed as
PTR_TO_SOCK_COMMON_OR_NULL, which type_is_sk_pointer() does not match
either, while it actually holds unconverted struct sk_buff bytes. Once
the NULL check has passed this is a type confusion, not just a leak of
kernel data.
Validate src_reg with check_reg_arg() and check the source pointer type
with atomic_ptr_type_ok() before the load again, mirroring
check_atomic_rmw(). Out-of-range register numbers are already rejected
earlier by check_and_resolve_insns() (commit 503d21ef8eac ("bpf: Do
register range validation early")), and the only exemption there,
is_stack_arg_ldx(), requires BPF_LDX | BPF_MEM | BPF_DW and thus never
matches a BPF_ATOMIC insn. atomic_ptr_type_ok() can therefore not
dereference register state out of bounds, that is, the out-of-bounds
read addressed by the Fixes commit below does not reappear (as proven
also via selftest). |
| In the Linux kernel, the following vulnerability has been resolved:
blk-cgroup: fix race between policy activation and blkg destruction
When switching an IO scheduler on a block device, blkcg_activate_policy()
allocates blkg_policy_data (pd) for all blkgs attached to the queue.
However, blkcg_activate_policy() may race with concurrent blkcg deletion,
leading to use-after-free and memory leak issues.
The use-after-free occurs in the following race:
T1 (blkcg_activate_policy):
- Successfully allocates pd for blkg1 (loop0->queue, blkcgA)
- Fails to allocate pd for blkg2 (loop0->queue, blkcgB)
- Enters the enomem rollback path to release blkg1 resources
T2 (blkcg deletion):
- blkcgA is deleted concurrently
- blkg1 is freed via blkg_free_workfn()
- blkg1->pd is freed
T1 (continued):
- Rollback path accesses blkg1->pd->online after pd is freed
- Triggers use-after-free
In addition, blkg_free_workfn() frees pd before removing the blkg from
q->blkg_list. This allows blkcg_activate_policy() to allocate a new pd
for a blkg that is being destroyed, leaving the newly allocated pd
unreachable when the blkg is finally freed.
Fix these races by extending blkcg_mutex coverage to serialize
blkcg_activate_policy() rollback and blkg destruction, ensuring pd
lifecycle is synchronized with blkg list visibility. |

platform/x86: asus-wmi: fix resource leaks on probe failure
During driver initialization in asus_wmi_add(), various subsystems are
registered sequentially. However, the error path labels are out of order
relative to the registration sequence.
Specifically:
1. If asus_wmi_custom_fan_curve_init() fails, the driver jumps to
fail_custom_fan_curve. Because this label is placed below fail_sysfs,
it bypasses the cleanup calls for the input device and sysfs groups,
which were successfully registered before, leaking those resources.
2. If asus_screenpad_init() fails, the driver jumps to fail_screenpad.
Because fail_screenpad is placed below fail_backlight, it bypasses the
cleanup calls for backlight and rfkill, leaking those resources.
Fix these resource leaks by reordering the error path labels in
asus_wmi_add() to match the exact reverse order of the resource
allocations. |

NFSv4.2: fix LAYOUTSTATS send buffer exhaustion
encode_layoutstats_maxsz budgets XDR_QUADLEN(PNFS_LAYOUTSTATS_MAXSIZE),
i.e. 256 bytes, for the layoutupdate4 body written by the layout driver.
The flexfiles record can exceed that.
ff_layout_encode_ff_layoutupdate() emits, per data server, a netaddr4,
an nfs_fh4, two ff_io_latency4, an nfstime4 and a bool. A data server
whose filehandle is NFS_MAXFHSIZE bytes long already accounts for 132 of
those bytes, and the two ff_io_latency4 at 64 bytes each, the nfstime4
and the bool add a further 144, so the body passes 256 bytes before the
netaddr4 is encoded at all. encode_layoutstats() additionally writes
the deviceid4 and the layoutupdate4 lou_type word, neither of which the
macro accounts for.
The filehandle and the address are both chosen by the server, through
LAYOUTGET and GETDEVICEINFO, so it can drive the encoder past the
end of the send buffer. xdr_reserve_space() returns NULL once that
happens, and the two ff_layout_encode_io_latency() calls run with
dss_info->mirror->lock held, so a NULL return there leaves the lock
permanently held.
Raise PNFS_LAYOUTSTATS_MAXSIZE to 384 so that the record fits inside the
reservation. |

irqchip/gic-v5: Check get_logical_index() return value in MADT IAFFID parsing
In gic_acpi_parse_iaffid() a given MADT GICC entry might not correspond
to a logical cpu recognized by the kernel, resulting in the cpu variable
initialization to an error value.
Currently, the get_logical_index() return value is not checked for failure,
which might result in out-of-bounds memory corruption while trying to
index a per_cpu variable array.
Add a check to evaluate get_logical_index() return value. |
| In the Linux kernel, the following vulnerability has been resolved:
irqchip/renesas-rzg2l: Fix loss of interrupt
rzg2l_clear_irq_int() and rzg2l_clear_tint_int() perform a
read-modify-write on the ISCR/TSCR status registers to clear the bit
for the interrupt just handled. Since these registers are
write-0-to-clear per bit, this is racy:
If another interrupt's status bit gets set between the read and the write,
that bit is written back as 0 by the software-constructed value, clearing
an interrupt that hasn't been serviced yet and losing it.
This can be reproduced by triggering multiple interrupts at once, e.g.:
gpioset -c gpiochip0 355=0 353=0 328=0 352=0
Fix this by writing back only the bit being cleared, with all other bits
set to 1, instead of read-modify-writing the whole register. Since 1-bits
are left unchanged by hardware, concurrently-set status bits for other
interrupts are preserved. |

clk: devres: fix cleanup in devm_clk_get_optional_enabled_with_rate()
devm_clk_get_optional_enabled_with_rate() registers its cleanup action
before setting the clock rate. If setting the rate fails, it attempts to
disable and unprepare a clock that was never enabled. This issue was
spotted while reviewing "rust: clk: add devres-managed clks" [1].
Register the cleanup action only after successfully preparing and enabling
the clock.

Fix the invalid memory access by validating the DMA index read from the
hardware before it is used as a queue index. An out-of-range value, such
as the 0xFFFFFFFF returned while the bus is hung, is now clamped so it can
no longer corrupt q->head or q->tail. In addition, check the bus_hung flag
in mt7921_mac_reset_work() before attempting the reset sequence, reject MCU
messages while the bus is hung, and install no-op bus operations when an
unrecoverable AER error is detected, preventing further invalid hardware
accesses.
Due to hardware limitations - such as the lack of a connected hardware
reset pin or the absence of host re-probe functionality - affected Wi-Fi
devices may not fully recover to a normal operational state after
certain errors, even with AER enabled. |
