NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-6.12.114-139.210 package and not the kernel-livepatch-6.12.114-139.210 package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.

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.
