  "details": "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.",
