Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: bpf: Send signals asynchronously if !preemptible BPF programs can execute in various contexts. When a program running in a non-preemptible context uses the bpfsendsignal function, issues may arise because this function can enter ...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: RISCV: Fixed sleeping in an invalid context in die. Die can be called within an exception handler, and therefore cannot sleep. However, die uses spinlockt, which can sleep when PREEMPTRT is enabled. This causes the following...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Netfilter: Use getrandomu32 instead of prandom. This issue may occur during the update of per-cpu rndstate from the user context, i.e., at the localout path. BUG: Using smpprocessorid in preemptible 00000000 code: nginx/2725...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: BPF: Using rawspinlockt in ringbuf. The function bpfringbufreserve is invoked from a tracepoint, which disables preemption. Using spinlockt in this context can lead to a “sleep in atomic” warning in the RT variant. This issue is...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: arm64/sve: Stale CPU state is discarded when handling SVE traps. The logic for handling SVE traps incorrectly manipulates the saved FPSIMD/SVE state. A race condition can occur, resulting in a task having TIFSVE set and...

CVE-2026-89753

A flaw was found in the Linux kernel's memory management subsystem. The shrinklruvec function, responsible for memory reclaim, fails to properly report Read-Copy-Update RCU task quiescent states on systems with preemption enabled. This can lead to RCU task stalls, causing system unresponsiveness ...
