In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Use current_context for safe per-CPU buffer swap The… (CVE-2026-74601)CVE-2026-74601 0 A vulnerability in the Linux kernel's ring buffer implementation allowed a race condition during per-CPU buffer swaps. The committing counter used to check if a buffer was actively written to could temporarily drop to zero during a write operation, enabling an unsafe swap and inconsistent buffer state.
