"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Zero queue and stack outputs on lock failure\n\nQueue and stack pop/peek helpers accept an uninitialized output buffer\nbecause the verifier expects the helper to initialize it. The empty-map\nerror path clears the buffer, but a failed lock acquisition returns\n-EBUSY without writing it.\n\nClear the output before returning -EBUSY so BPF programs cannot observe\nuninitialized stack contents after a failed helper call."
