CVE-2026-74601

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Use currentcontext for safe per-CPU buffer swap The ringbufferswapcpu function currently checks the per-CPU committing counter to determine if a buffer is actively being written to before performing the swap. However...

CVE-2026-74601

CVE-2026-74601 is a race condition in the Linux kernel ring-buffer (tracing subsystem). The ring_buffer_swap_cpu() function checks a per-CPU committing counter to determine if a buffer is actively being written to before performing a swap. However, this counter can temporarily drop to 0 during a ...

UBUNTU-CVE-2026-74286

In the Linux kernel, the following vulnerability has been resolved: net: pfcp: allocate per-cpu tstats for PFCP netdevs PFCP uses devgettstats64 as its ndogetstats64 callback, but pfcplinksetup does not request NETDEVPCPUSTATTSTATS. The net core therefore leaves dev-tstats NULL for PFCP devices...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: AppArmor: Avoid per-cpu hold underflow in aagetbuffer. When aagetbuffer retrieves data from the per-cpu list, it conditionally decreases cache-hold. If hold reaches 0 while count remains non-zero, the unsigned decrement wraps to...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ipv6: A bug in rt6getpcpuroute under PREEMPTRT has been fixed. On PREEMPTRT kernels, after rt6getpcpuroute returns NULL, the current task can be preempted. Another task running on the same CPU may then execute rt6makepcpuroute an...

In the Linux kernel, the following vulnerability has been resolved: tcp: fix stale per-CPU tcptwisn leak enabling ISN prediction Blamed commit moved the TIMEWAIT-derived ISN from the skb control block to a per-CPU variable, assuming the value would always be consumed by tcpconnrequest for the sam...

CVE-2026-63799

A flaw was found in the Linux kernel's scheduler component. A local attacker could exploit an out-of-bounds write vulnerability during the creation or execution of a new task in per-CPU mode, specifically when an internal identifier is unassigned. This can lead to a bounded memory corruption, whe...
