Description OSIDB Bzimport 2026-08-28 07:44:47 UTC 
In the Linux kernel, the following vulnerability has been resolved:

tracing/probes: Remove WARN_ON_ONCE from parse_btf_arg

Sashiko found that user can cause this WARN_ON_ONCE() easily
with adding a kprobe event based on a raw address with BTF
parameter.

Since this is not an unexpected condition, remove the
WARN_ON_ONCE().
