AZL-67731 CVE-2023-52676 affecting package kernel 5.15.200.1-1

In the Linux kernel, the following vulnerability has been resolved: bpf: Guard stack limits against 32bit overflow This patch promotes the arithmetic around checking stack bounds to be done in the 64-bit domain, instead of the current 32bit. The arithmetic implies adding together a 64-bit registe...

kernel: bpf: Skip invalid kfunc call in backtrack_insn

In the Linux kernel, the following vulnerability has been resolved: bpf: Skip invalid kfunc call in backtrackinsn The verifier skips invalid kfunc call in checkkfunccall, which would be captured in fixupkfunccall if such insn is not eliminated by dead code elimination. However, this can lead to t...

kernel: bpf: Fix reference state management for synchronous callbacks

A flaw was found in the Linux kernel's BPF verifier. The verifier incorrectly handles reference state management for synchronous callbacks that execute multiple times foreach style helpers. This can lead to reference leaks when callbacks acquire references, or double-free conditions when callback...
