🚨 CVE-2026-45949
In the Linux kernel, the following vulnerability has been resolved:
hwrng: core - use RCU and work_struct to fix race condition

exits. Since hwrng_unregister() reads hwrng_fill outside the rng_mutex
lock, a...
🚨 CVE-2026-45953
In the Linux kernel, the following vulnerability has been resolved:
md/raid5: fix IO hang with degraded array with llbitmap

rcw, as bitmap_ops->blocks_synced() is checked in handle_stripe_dirtying()...
🚨 CVE-2026-45961
In the Linux kernel, the following vulnerability has been resolved:
gfs2: fix memory leaks in gfs2_fill_super error path
Fix two memory leaks in the gfs2_fill_super() error handling path when

First leak: kthread objects...
🚨 CVE-2026-45897
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_counter: serialize reset with spinlock

operations, preventing concurrent dump-and-reset from underrunning
values.
The lock is taken...
🚨 CVE-2026-45899
In the Linux kernel, the following vulnerability has been resolved:
ext4: drop extent cache when splitting extent fails
When the split extent fails, we might leave some extents still being
processed and return an error directly, which will result in stale
extent entries...
🚨 CVE-2026-45901
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: revert commit_mutex usage in reset path
It causes circular lock dependency between commit_mutex, nfnl_subsys_ipset
and nlk_cb_mutex when nft reset, ipset list, and iptables-nft with '-m...
🚨 CVE-2026-45904
In the Linux kernel, the following vulnerability has been resolved:
powerpc/eeh: fix recursive pci_lock_rescan_remove locking in EEH event handling

hotplug safe") restructured the EEH driver to improve...
🚨 CVE-2026-45912
In the Linux kernel, the following vulnerability has been resolved:
ext4: don't cache extent during splitting extent
Caching extents during the splitting process is risky, as it may result
in stale extents remaining in the status tree. Moreover, in most cases,
the...
🚨 CVE-2026-45913
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...
🚨 CVE-2026-45915
In the Linux kernel, the following vulnerability has been resolved:
fat: avoid parent link count underflow in rmdir
Corrupted FAT images can leave a directory inode with an incorrect
i_nlink (e.g. 2 even though subdirectories exist). rmdir then
unconditionally calls...
🚨 CVE-2026-45917
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...
🚨 CVE-2026-45919
In the Linux kernel, the following vulnerability has been resolved:
sched/rt: Skip currently executing CPU in rto_next_cpu()
CPU0 becomes overloaded when hosting a CPU-bound RT task, a non-CPU-bound
RT task, and a CFS task stuck in kernel space. When other CPUs switch from
RT...
🚨 CVE-2026-45920
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix dirtyclusters double decrement on fs shutdown
fstests test generic/388 occasionally reproduces a warning in

🚨 CVE-2026-45923
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...
🚨 CVE-2026-45925
In the Linux kernel, the following vulnerability has been resolved:
thermal/of: Fix reference leak in thermal_of_cm_lookup()

never released.
Use the __free(device_node) cleanup attribute to automatically...
🚨 CVE-2026-45940
In the Linux kernel, the following vulnerability has been resolved:
net: stmmac: fix oops when split header is enabled
For GMAC4, when split header is enabled, in some rare cases, the
hardware does not fill buf2 of the first descriptor with payload.
Thus we cannot assume buf2...
