Details

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]

Severity

5.5 (Medium)
