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