| Unrestricted upload of file with dangerous type in Azure Orbital Spatio allows an unauthorized attacker to execute code over a network. |
| In the Linux kernel, the following vulnerability has been resolved:
mtd: parsers: Fix memory leak in mtd_parser_tplink_safeloader_parse()
The function mtd_parser_tplink_safeloader_parse() allocates buf via
mtd_parser_tplink_safeloader_read_table(). If the allocation for
parts[idx].name fails inside the loop, the code jumps to the err_free
label without freeing buf, leading to a memory leak.
Fix this by freeing the temporary buffer buf in the err_free label.
Compile tested only. Issue found using a prototype static analysis tool
and code review. |
| In the Linux kernel, the following vulnerability has been resolved:
net: usb: catc: enable basic endpoint checking
catc_probe() fills three URBs with hardcoded endpoint pipes without
verifying the endpoint descriptors:
- usb_sndbulkpipe(usbdev, 1) and usb_rcvbulkpipe(usbdev, 1) for TX/RX
- usb_rcvintpipe(usbdev, 2) for interrupt status
A malformed USB device can present these endpoints with transfer types
that differ from what the driver assumes.
Add a catc_usb_ep enum for endpoint numbers, replacing magic constants
throughout. Add usb_check_bulk_endpoints() and usb_check_int_endpoints()
calls after usb_set_interface() to verify endpoint types before use,
rejecting devices with mismatched descriptors at probe time.
Similar to
- commit 90b7f2961798 ("net: usb: rtl8150: enable basic endpoint checking")
which fixed the issue in rtl8150. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Require frozen map for calculating map hash
Currently, bpf_map_get_info_by_fd calculates and caches the hash of the
map regardless of the map's frozen state.
This leads to a TOCTOU bug where userspace can call
BPF_OBJ_GET_INFO_BY_FD to cache the hash and then modify the map
contents before freezing.
Therefore, a trusted loader can be tricked into verifying the stale hash
while loading the modified contents.
Fix this by returning -EPERM if the map is not frozen when the hash is
requested. This ensures the hash is only generated for the final,
immutable state of the map. |
| In the Linux kernel, the following vulnerability has been resolved:
media: chips-media: wave5: Fix memory leak on codec_info allocation failure
In wave5_vpu_open_enc() and wave5_vpu_open_dec(), a vpu instance is
allocated via kzalloc(). If the subsequent allocation for inst->codec_info
fails, the functions return -ENOMEM without freeing the previously
allocated instance, causing a memory leak.
Fix this by calling kfree() on the instance in this error path to ensure
it is properly released. |
| In the Linux kernel, the following vulnerability has been resolved:
ovpn: fix possible use-after-free in ovpn_net_xmit
When building the skb_list in ovpn_net_xmit, skb_share_check will free
the original skb if it is shared. The current implementation continues
to use the stale skb pointer for subsequent operations:
- peer lookup,
- skb_dst_drop (even though all segments produced by skb_gso_segment
will have a dst attached),
- ovpn_peer_stats_increment_tx.
Fix this by moving the peer lookup and skb_dst_drop before segmentation
so that the original skb is still valid when used. Return early if all
segments fail skb_share_check and the list ends up empty.
Also switch ovpn_peer_stats_increment_tx to use skb_list.next; the next
patch fixes the stats logic. |
| In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Fix slab-out-of-bounds read in DeleteIndexEntryRoot
In the 'DeleteIndexEntryRoot' case of the 'do_action' function, the
entry size ('esize') is retrieved from the log record without adequate
bounds checking.
Specifically, the code calculates the end of the entry ('e2') using:
e2 = Add2Ptr(e1, esize);
It then calculates the size for memmove using 'PtrOffset(e2, ...)',
which subtracts the end pointer from the buffer limit. If 'esize' is
maliciously large, 'e2' exceeds the used buffer size. This results in
a negative offset which, when cast to size_t for memmove, interprets
as a massive unsigned integer, leading to a heap buffer overflow.
This commit adds a check to ensure that the entry size ('esize') strictly
fits within the remaining used space of the index header before performing
memory operations. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: inside-secure/eip93 - fix kernel panic in driver detach
During driver detach, the same hash algorithm is unregistered multiple
times due to a wrong iterator. |
| In the Linux kernel, the following vulnerability has been resolved:
power: supply: pm8916_lbc: Fix use-after-free in power_supply_changed()
Using the `devm_` variant for requesting IRQ _before_ the `devm_`
variant for allocating/registering the `power_supply` handle, means that
the `power_supply` handle will be deallocated/unregistered _before_ the
interrupt handler (since `devm_` naturally deallocates in reverse
allocation order). This means that during removal, there is a race
condition where an interrupt can fire just _after_ the `power_supply`
handle has been freed, *but* just _before_ the corresponding
unregistration of the IRQ handler has run.
This will lead to the IRQ handler calling `power_supply_changed()` with
a freed `power_supply` handle. Which usually crashes the system or
otherwise silently corrupts the memory...
Note that there is a similar situation which can also happen during
`probe()`; the possibility of an interrupt firing _before_ registering
the `power_supply` handle. This would then lead to the nasty situation
of using the `power_supply` handle *uninitialized* in
`power_supply_changed()`.
Fix this racy use-after-free by making sure the IRQ is requested _after_
the registration of the `power_supply` handle. |
| In the Linux kernel, the following vulnerability has been resolved:
gpib: Fix memory leak in ni_usb_init()
In ni_usb_init(), if ni_usb_setup_init() fails, the function returns
-EFAULT without freeing the allocated writes buffer, leading to a
memory leak.
Additionally, ni_usb_setup_init() returns 0 on failure, which causes
ni_usb_init() to return -EFAULT, an inappropriate error code for this
situation.
Fix the leak by freeing writes in the error path. Modify
ni_usb_setup_init() to return -EINVAL on failure and propagate this
error code in ni_usb_init(). |
| In the Linux kernel, the following vulnerability has been resolved:
tpm: tpm_i2c_infineon: Fix locality leak on get_burstcount() failure
get_burstcount() can return -EBUSY on timeout. When this happens, the
function returns directly without releasing the locality that was
acquired at the beginning of tpm_tis_i2c_send().
Use goto out_err to ensure proper cleanup when get_burstcount() fails. |
| Improper Certificate Validation vulnerability in Erlang OTP public_key (pubkey_ocsp module) allows forged OCSP responses signed with an expired responder certificate to be accepted as valid.
OCSP response verification in pubkey_ocsp:verify_response/5 and pubkey_ocsp:is_authorized_responder/3 in lib/public_key/src/pubkey_ocsp.erl does not check the validity period (notBefore/notAfter) of the OCSP responder certificate. An attacker who has obtained the private key of an expired CA-designated OCSP responder certificate can forge OCSP responses that Erlang/OTP accepts as valid.
This affects TLS clients using OCSP stapling via the ssl application: a malicious or compromised server can present a revoked TLS certificate together with a forged OCSP response signed by an expired responder key, and the client will accept the revoked certificate as valid. It also affects applications calling public_key:pkix_ocsp_validate/5 directly, where the impact depends on the use case — server-side client certificate validation using this API may allow authentication bypass with a revoked client certificate.
This issue affects OTP from OTP 27.0 before OTP 27.3.4.12, 28.5.0.1, and 29.0.1 corresponding to public_key from 1.16 before 1.17.1.3, 1.20.3.1, and 1.21.1. |
| libusb before version 1.0.30 contains a NULL pointer dereference vulnerability that allows attackers to crash applications by supplying a malformed USB configuration descriptor where an interface claims bNumEndpoints greater than zero but is followed by a class-specific descriptor whose bLength exceeds the remaining buffer size, causing parse_interface() to return early without allocating the endpoint array. Attackers can exploit this flaw through libusb_get_active_config_descriptor or libusb_get_config_descriptor by providing crafted descriptors via virtualized USB passthrough, file-based descriptor parsing, or network sources, causing any application iterating over endpoints to dereference a NULL endpoint pointer and crash. |
| Improper neutralization of special elements used in a command ('command injection') in M365 Copilot allows an unauthorized attacker to disclose information over a network. |
| Command injection in Raynet rvia version 12.6.4392.49-amd64.deb allows adversaries to execute arbitrary Java code via a crafted path that matches the improperly terminated search criteria of rvia's Java search using the find command. |
| A NULL pointer dereference in GPAC MP4Box: when parsing certain truncated MP4 files, an unknown/invalid stsd entry can result in missing descriptor fields (e.g., codec/mime/profile strings). gf_media_map_esd then calls strlen() on a NULL pointer, triggering a crash (ASan SEGV). |
| In the Linux kernel, the following vulnerability has been resolved:
drm/display/dp_mst: Add protection against 0 vcpi
When releasing a timeslot there is a slight chance we may end up
with the wrong payload mask due to overflow if the delayed_destroy_work
ends up coming into play after a DP 2.1 monitor gets disconnected
which causes vcpi to become 0 then we try to make the payload =
~BIT(vcpi - 1) which is a negative shift. VCPI id should never
really be 0 hence skip changing the payload mask if VCPI is 0.
Otherwise it leads to

| In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: Fix NULL pointer dereference on panthor_fw_unplug
This patch removes the MCU halt and wait for halt procedures during
panthor_fw_unplug() as the MCU can be in a variety of states or the FW
may not even be loaded/initialized at all, the latter of which can lead
to a NULL pointer dereference.
It should be safe on unplug to just disable the MCU without waiting for
it to halt as it may not be able to. |
| In the Linux kernel, the following vulnerability has been resolved:
mctp i2c: initialise event handler read bytes
Set a 0xff value for i2c reads of an mctp-i2c device. Otherwise reads
will return "val" from the i2c bus driver. For i2c-aspeed and
i2c-npcm7xx that is a stack uninitialised u8.
Tested with "i2ctransfer -y 1 r10@0x34" where 0x34 is a mctp-i2c
instance, now it returns all 0xff. |
| In the Linux kernel, the following vulnerability has been resolved:
serial: caif: fix use-after-free in caif_serial ldisc_close()
There is a use-after-free bug in caif_serial where handle_tx() may
access ser->tty after the tty has been freed.
The race condition occurs between ldisc_close() and packet transmission:
CPU 0 (close) CPU 1 (xmit)
------------- ------------
ldisc_close()
tty_kref_put(ser->tty)
[tty may be freed here]
<-- race window -->
caif_xmit()
handle_tx()
tty = ser->tty // dangling ptr
tty->ops->write() // UAF!
schedule_work()
ser_release()
unregister_netdevice()
The root cause is that tty_kref_put() is called in ldisc_close() while
the network device is still active and can receive packets.
Since ser and tty have a 1:1 binding relationship with consistent
lifecycles (ser is allocated in ldisc_open and freed in ser_release
via unregister_netdevice, and each ser binds exactly one tty), we can
safely defer the tty reference release to ser_release() where the
network device is unregistered.
Fix this by moving tty_kref_put() from ldisc_close() to ser_release(),
after unregister_netdevice(). This ensures the tty reference is held
as long as the network device exists, preventing the UAF.
Note: We save ser->tty before unregister_netdevice() because ser is
embedded in netdev's private data and will be freed along with netdev
(needs_free_netdev = true).
How to reproduce: Add mdelay(500) at the beginning of ldisc_close()
to widen the race window, then run the reproducer program [1].
Note: There is a separate deadloop issue in handle_tx() when using
PORT_UNKNOWN serial ports (e.g., /dev/ttyS3 in QEMU without proper
serial backend). This deadloop exists even without this patch,
and is likely caused by inconsistency between uart_write_room() and
uart_write() in serial core. It has been addressed in a separate
patch [2].
