Deskripsi CVE
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.
