CVE-2026-80563

A flaw was found in the Linux kernel's gpio: sloppy-logic-analyzer component. A local attacker with root privileges can exploit a race condition during the unbinding of a platform device. This vulnerability allows writing into memory that has already been freed, which can lead to system instabili...

CVE-2026-74746

A flaw was found in the netfilter flowtable component of the Linux kernel. This vulnerability occurs due to a timing issue where the system's garbage collection can free a network flow while it is still being set up. This can lead to a 'use-after-free' condition, where the system attempts to acce...

CVE-2026-80572

A flaw was found in the Linux kernel's byd input driver. A race condition exists during device disconnection where the byddisconnect function frees private data before ensuring that a timer callback, bydcleartouch, has completed. This can lead to the callback attempting to access memory after it...

libexpat: libexpat: Memory corruption vulnerability allows arbitrary code execution or denial of service

A flaw was found in libexpat. The library's handling of custom encoding callbacks lacks proper tracking of handler call depth, which can lead to a use-after-free vulnerability. This memory corruption flaw could allow a local attacker to cause a denial of service or potentially execute arbitrary...

Important: Red Hat Security Advisory: kernel security update

kernel: net: ipv6: use-after-free in fib6_rule_suppress due to stale res->rt6 pointer

A use-after-free vulnerability was found in the Linux kernel's IPv6 FIB rule lookup path. In fib6rulesuppress, when a route is suppressed and released via ip6rtputflags, the res-rt6 pointer is not cleared. If no later rule supplies a replacement route, fib6rulelookup returns the stale freed rt6in...

CVE-2026-80553

A flaw was found in the s390/vfioccw component of the Linux kernel. This vulnerability arises from the improper management of workqueues, where existing tasks might not be canceled before associated resources are released. A local attacker could potentially leverage this issue to trigger a...

CVE-2026-74743

A flaw was found in the Linux kernel's macvlan component. The macvlan component incorrectly initializes network packet buffer skb headroom and tailroom values, failing to inherit them from the underlying network device. This can occur when the underlying device requires additional space for heade...

CVE-2026-74744

A flaw was found in the Linux kernel's ipvlan component. The ipvlan devices do not properly inherit neededheadroom and neededtailroom from the physical device phydev. This can lead to insufficient space being reserved for packet headers and trailers, potentially causing memory corruption, such as...

CVE-2026-74753

A flaw was found in the Linux kernel's performance monitoring perf subsystem. This vulnerability allows a local attacker to trigger a use-after-free condition by improperly handling exited events as group leaders. Successful exploitation could lead to a system crash, resulting in a denial of...

EUVD-2026-66494

In the Linux kernel, the following vulnerability has been resolved: fbdev: clear fbinfo-mode before deleting a videomode fbsetvar can delete a mode from info-modelist when userspace passes FBACTIVATEINVMODE through FBIOPUTVSCREENINFO. The code checks that the mode being deleted is not the current...

EUVD-2026-66504

In the Linux kernel, the following vulnerability has been resolved: block: stop the timeout timer when releasing a never added disk diskrelease undoes blkmqinitallocatedqueue for a disk whose probe failed before adddisk, but it only calls blkmqexitqueue. Nothing there stops q-timeout, and that...

EUVD-2026-66468

In the Linux kernel, the following vulnerability has been resolved: s390/vfioccw: Cancel existing workqueues The initialization of the iowork and crwwork workqueues begs the question of whether they should be un-initialized. Add the corresponding cleanup tags in releasedev to ensure work isn't...
