Official 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.
