CVE-2025-39990 (opens in a new tab)Amendment
The Centos security team deemed this advisory irrelevant for Centos:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream rv package and not the rv package as distributed by Centos.
In the Linux kernel, the following vulnerability has been resolved:
bpf: Check the helper function is valid in get_helper_proto
kernel test robot reported verifier bug [1] where the helper func pointer could be NULL due to disabled config option.
As Alexei suggested we could check on that in get_helper_proto directly. Marking tail_call helper func with BPF_PTR_POISON, because it is unused by design.
