Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> selinux: fix avdcache auditing<br /> <br /> The per-task avdcache was incorrectly saving and reusing the<br /> audited vector computed by avc_audit_required() rather than<br /> recomputing based on the currently requested permissions and<br /> distinguishing the denied versus allowed cases. As a result,<br /> some permission checks were not being audited, e.g.<br /> directory write checks after a previously cached directory<br /> search check.<br /> <br /> [PM: line wrap tweaks]
