kernel: net/sched: act_api: use RCU with deferred freeing for action lifecycle

A flaw was found in the Linux kernel's networking scheduler. A race condition, which is a problem that occurs when multiple operations try to access the same resource at the same time, exists when network filter operations are run concurrently. This can lead to a Use-After-Free UAF vulnerability,...

SUSE CVE-2026-72181

In the Linux kernel, the following vulnerability has been resolved: mips: sched: Fix CPUMASKOFFSTACK memory corruption This patch addresses a critical memory management flaw. When CONFIGCPUMASKOFFSTACK is enabled, cpumaskvart is a pointer. Consequently, sizeofnewmask evaluates to the pointer size...

CVE-2026-80630

A flaw was found in the Linux kernel's fqcodel Fair Queueing Controlled Delay network scheduler. When fqcodel drops packets during a peek operation, it incorrectly calls qdisctreereducebacklog before restoring the queue length. This can lead to the parent's class being mistakenly deactivated,...

The vulnerability of the mm_cid_do_fixuptasks_to_cpus() function in the kernel/sched/core.c module, which is part of the Linux operating system’s resource management support, allows a hacker to trigger a service failure.

The vulnerability of the mmciddofixuptaskstocpus function in the kernel/sched/core.c module, which is part of the Linux operating system’s resource management support mechanism, involves executing a loop with an unreachable exit condition an “infinite loop”. Exploiting this vulnerability could...

SUSE CVE-2026-74638

In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Serialize the scheduler timeout handlers V3D exposes several independent hardware queues BIN, RENDER, TFU and CSD but has only a single, global reset. A timeout on any one queue therefore has to stop, reset and restart t...
