CVE-2026-89580

CVE-2026-89580 is a race condition in the Linux kernel's BPF subsystem , specifically in __bpf_get_stack. A preemptible BPF program (e.g., a non-sleepable raw tracepoint program on a PREEMPT kernel) can be scheduled out between obtaining a per-CPU perf_callchain_entry buffer and copying it. Anoth...

AZL-97146 CVE-2026-74601 affecting package kernel for versions less than 6.6.157.1-1

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 affects the Linux kernel tracing ring-buffer subsystem. The ring_buffer_swap_cpu() function relies on a per-CPU committing counter to determine whether a buffer is actively being written to before performing a swap. However, the counter can temporarily drop to zero during rb_move_t...

OpenTelemetry eBPF Instrumentation: CPU-mismatch fallback uses 256-byte buffer with 8KB size

Summary The per-CPU message-buffer fallback path uses a 256-byte backup buffer but preserves the original payload size, which can be up to 8KB. If a CPU mismatch occurs, OBI can read beyond the fallback buffer and leak adjacent memory into telemetry. Details...
