Description OSIDB Bzimport 2026-07-19 10:01:34 UTC
In the Linux kernel, the following vulnerability has been resolved:

selinux: fix avdcache auditing

The per-task avdcache was incorrectly saving and reusing the
audited vector computed by avc_audit_required() rather than
recomputing based on the currently requested permissions and
distinguishing the denied versus allowed cases. As a result,
some permission checks were not being audited, e.g.
directory write checks after a previously cached directory
search check.

[PM: line wrap tweaks]
