| In the Linux kernel, the following vulnerability has been resolved:
smack: /smack/doi: accept previously used values
Writing to /smack/doi a value that has ever been
written there in the past disables networking for
non-ambient labels.
E.g.
# cat /smack/doi
3
# netlabelctl -p cipso list
Configured CIPSO mappings (1)
DOI value : 3
mapping type : PASS_THROUGH
# netlabelctl -p map list
Configured NetLabel domain mappings (3)
domain: "_" (IPv4)
protocol: UNLABELED
domain: DEFAULT (IPv4)
protocol: CIPSO, DOI = 3
domain: DEFAULT (IPv6)
protocol: UNLABELED
# cat /smack/ambient

# cat /proc/$$/attr/smack/current
_
# ping -c1 10.1.95.12
64 bytes from 10.1.95.12: icmp_seq=1 ttl=64 time=0.964 ms
# echo foo >/proc/$$/attr/smack/current
# ping -c1 10.1.95.12
64 bytes from 10.1.95.12: icmp_seq=1 ttl=64 time=0.956 ms

# echo 4 >/smack/doi
# echo 3 >/smack/doi

# echo 3 >/smack/doi
!> [ 249.402261] smk_cipso_doi:678 remove rc = -2
!> [ 249.402261] smk_cipso_doi:691 cipso add rc = -17
# ping -c1 10.1.95.12
!!> ping: 10.1.95.12: Address family for hostname not supported
# echo _ >/proc/$$/attr/smack/current
# ping -c1 10.1.95.12
64 bytes from 10.1.95.12: icmp_seq=1 ttl=64 time=0.617 ms
This happens because Smack keeps decommissioned DOIs,
fails to re-add them, and consequently refuses to add
the “default” domain map:
# netlabelctl -p cipso list
Configured CIPSO mappings (2)
DOI value : 3
mapping type : PASS_THROUGH
DOI value : 4
mapping type : PASS_THROUGH
# netlabelctl -p map list
Configured NetLabel domain mappings (2)
domain: "_" (IPv4)
protocol: UNLABELED
!> (no ipv4 map for default domain here)
domain: DEFAULT (IPv6)
protocol: UNLABELED
Fix by clearing decommissioned DOI definitions and
serializing concurrent DOI updates with a new lock.
Also:
- allow /smack/doi to live unconfigured, since
adding a map (netlbl_cfg_cipsov4_map_add) may fail.
CIPSO_V4_DOI_UNKNOWN(0) indicates the unconfigured DOI
- add new DOI before removing the old default map,
so the old map remains if the add fails

| In the Linux kernel, the following vulnerability has been resolved:
power: supply: wm97xx: Fix NULL pointer dereference in power_supply_changed()
In `probe()`, `request_irq()` is called before allocating/registering a
`power_supply` handle. If an interrupt is fired between the call to
`request_irq()` and `power_supply_register()`, the `power_supply` handle
will be used uninitialized in `power_supply_changed()` in
`wm97xx_bat_update()` (triggered from the interrupt handler). This will
lead to a `NULL` pointer dereference since
Fix this racy `NULL` pointer dereference by making sure the IRQ is
requested _after_ the registration of the `power_supply` handle. Since
the IRQ is the last thing requests in the `probe()` now, remove the
error path for freeing it. Instead add one for unregistering the
`power_supply` handle when IRQ request fails. |
| In the Linux kernel, the following vulnerability has been resolved:
tpm: st33zp24: Fix missing cleanup on get_burstcount() error
get_burstcount() can return -EBUSY on timeout. When this happens,
st33zp24_send() returns directly without releasing the locality
acquired earlier.
Use goto out_err to ensure proper cleanup when get_burstcount() fails. |
| In the Linux kernel, the following vulnerability has been resolved:
arm64/gcs: Fix error handling in arch_set_shadow_stack_status()
alloc_gcs() returns an error-encoded pointer on failure, which comes
from do_mmap(), not NULL.
The current NULL check fails to detect errors, which could lead to using
an invalid GCS address.
Use IS_ERR_VALUE() to properly detect errors, consistent with the
check in gcs_alloc_thread_stack(). |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Fix watch_id bounds checking in debug address watch v2
The address watch clear code receives watch_id as an unsigned value
(u32), but some helper functions were using a signed int and checked
bits by shifting with watch_id.
If a very large watch_id is passed from userspace, it can be converted
to a negative value. This can cause invalid shifts and may access
memory outside the watch_points array.
drm/amdkfd: Fix watch_id bounds checking in debug address watch v2
Fix this by checking that watch_id is within MAX_WATCH_ADDRESSES before
using it. Also use BIT(watch_id) to test and clear bits safely.
This keeps the behavior unchanged for valid watch IDs and avoids
undefined behavior for invalid ones.
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_debug.c:448
kfd_dbg_trap_clear_dev_address_watch() error: buffer overflow
'pdd->watch_points' 4 <= u32max user_rl='0-3,2147483648-u32max' uncapped

434 uint32_t watch_id)
435 {
436 int r;
437
438 if (!kfd_dbg_owns_dev_watch_id(pdd, watch_id))
kfd_dbg_owns_dev_watch_id() doesn't check for negative values so if
watch_id is larger than INT_MAX it leads to a buffer overflow.
(Negative shifts are undefined).
439 return -EINVAL;
440
441 if (!pdd->dev->kfd->shared_resources.enable_mes) {
442 r = debug_lock_and_unmap(pdd->dev->dqm);
443 if (r)
444 return r;
445 }
446
447 amdgpu_gfx_off_ctrl(pdd->dev->adev, false);
--> 448 pdd->watch_points[watch_id] = pdd->dev->kfd2kgd->clear_address_watch(
449 pdd->dev->adev,
450 watch_id);
v2: (as per, Jonathan Kim)
- Add early watch_id >= MAX_WATCH_ADDRESSES validation in the set path to
match the clear path.
- Drop the redundant bounds check in kfd_dbg_owns_dev_watch_id(). |
| In the Linux kernel, the following vulnerability has been resolved:
xfrm: fix ip_rt_bug race in icmp_route_lookup reverse path
icmp_route_lookup() performs multiple route lookups to find a suitable
route for sending ICMP error messages, with special handling for XFRM
(IPsec) policies.
The lookup sequence is:
1. First, lookup output route for ICMP reply (dst = original src)
2. Pass through xfrm_lookup() for policy check
3. If blocked (-EPERM) or dst is not local, enter "reverse path"
4. In reverse path, call xfrm_decode_session_reverse() to get fl4_dec
which reverses the original packet's flow (saddr<->daddr swapped)
5. If fl4_dec.saddr is local (we are the original destination), use
__ip_route_output_key() for output route lookup
6. If fl4_dec.saddr is NOT local (we are a forwarding node), use
ip_route_input() to simulate the reverse packet's input path
7. Finally, pass rt2 through xfrm_lookup() with XFRM_LOOKUP_ICMP flag
The bug occurs in step 6: ip_route_input() is called with fl4_dec.daddr
(original packet's source) as destination. If this address becomes local
between the initial check and ip_route_input() call (e.g., due to
concurrent "ip addr add"), ip_route_input() returns a LOCAL route with
dst.output set to ip_rt_bug.
This route is then used for ICMP output, causing dst_output() to call
ip_rt_bug(), triggering a WARN_ON:

| In the Linux kernel, the following vulnerability has been resolved:
power: supply: pf1550: 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:
net: bridge: mcast: always update mdb_n_entries for vlan contexts
syzbot triggered a warning[1] about the number of mdb entries in a context.
It turned out that there are multiple ways to trigger that warning today
(some got added during the years), the root cause of the problem is that
the increase is done conditionally, and over the years these different
conditions increased so there were new ways to trigger the warning, that is
to do a decrease which wasn't paired with a previous increase.
For example one way to trigger it is with flush:
$ ip l add br0 up type bridge vlan_filtering 1 mcast_snooping 1
$ ip l add dumdum up master br0 type dummy
$ bridge mdb add dev br0 port dumdum grp 239.0.0.1 permanent vid 1
$ ip link set dev br0 down
$ ip link set dev br0 type bridge mcast_vlan_snooping 1
^^^^ this will enable snooping, but will not update mdb_n_entries
because in __br_multicast_enable_port_ctx() we check !netif_running
$ bridge mdb flush dev br0
^^^ this will trigger the warning because it will delete the pg which
we added above, which will try to decrease mdb_n_entries
Fix the problem by removing the conditional increase and always keep the
count up-to-date while the vlan exists. In order to do that we have to
first initialize it on port-vlan context creation, and then always increase
or decrease the value regardless of mcast options. To keep the current
behaviour we have to enforce the mdb limit only if the context is port's or
if the port-vlan's mcast snooping is enabled.

| In the Linux kernel, the following vulnerability has been resolved:
ipvs: do not keep dest_dst if dev is going down
There is race between the netdev notifier ip_vs_dst_event()
and the code that caches dst with dev that is going down.
As the FIB can be notified for the closed device after our
handler finishes, it is possible valid route to be returned
and cached resuling in a leaked dev reference until the dest
is not removed.
To prevent new dest_dst to be attached to dest just after the
handler dropped the old one, add a netif_running() check
to make sure the notifier handler is not currently running
for device that is closing. |
| In the Linux kernel, the following vulnerability has been resolved:
bonding: alb: fix UAF in rlb_arp_recv during bond up/down
The ALB RX path may access rx_hashtbl concurrently with bond
teardown. During rapid bond up/down cycles, rlb_deinitialize()
frees rx_hashtbl while RX handlers are still running, leading
to a null pointer dereference detected by KASAN.
However, the root cause is that rlb_arp_recv() can still be accessed
after setting recv_probe to NULL, which is actually a use-after-free
(UAF) issue. That is the reason for using the referenced commit in the
Fixes tag.

The issue is reproducible by repeatedly running
ip link set bond0 up/down while receiving ARP messages, where
rlb_arp_recv() can race with rlb_deinitialize() and dereference
a freed rx_hashtbl entry.
Fix this by setting recv_probe to NULL and then calling
synchronize_net() to wait for any concurrent RX processing to finish.
This ensures that no RX handler can access rx_hashtbl after it is freed
in bond_alb_deinitialize(). |
| In the Linux kernel, the following vulnerability has been resolved:
net: qrtr: ns: Limit the total number of nodes
Currently, the nameserver doesn't limit the number of nodes it handles.
This can be an attack vector if a malicious client starts registering
random nodes, leading to memory exhaustion.
Hence, limit the maximum number of nodes to 64. Note that, limit of 64 is
chosen based on the current platform requirements. If requirement changes
in the future, this limit can be increased. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Use kvfree instead of kfree in amdgpu_gmc_get_nps_memranges()
amdgpu_discovery_get_nps_info() internally allocates memory for ranges
using kvcalloc(), which may use vmalloc() for large allocation. Using
kfree() to release vmalloc memory will lead to a memory corruption.
Use kvfree() to safely handle both kmalloc and vmalloc allocations.
Compile tested only. Issue found using a prototype static analysis tool
and code review. |

crypto: inside-secure/eip93 - unregister only available algorithm
EIP93 has an options register. This register indicates which crypto
algorithms are implemented in silicon. Supported algorithms are
registered on this basis. Unregister algorithms on the same basis.
Currently, all algorithms are unregistered, even those not supported
by HW. This results in panic on platforms that don't have all options
