Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> debugobjects: Do not fill_pool() if pi_blocked_on<br /> <br /> On RT enabled kernels, fill_pool() ends up calling rtlock_lock(), which<br /> asserts if current::pi_blocked_on is set, because a task can obviously only<br /> block on one lock as otherwise the priority inheritenace chain gets<br /> corrupted.<br /> <br /> Prevent this by expanding the conditional to take current::pi_blocked_on<br /> into account.
