CVE-2026-92520
CVE-2026-92520 updated by NVD
Summary
In the Linux kernel, the following vulnerability has been resolved: bpf: Zero queue and stack outputs on lock failure Queue and stack pop/peek helpers accept an uninitialized output buffer because the verifier expects the helper to initialize it. The empty-map error path clears the buffer, but a failed lock acquisition returns -EBUSY without writing it. Clear the output before returning -EBUSY so BPF programs cannot observe uninitialized stack contents after a failed helper call.
