- Summary
- debugobjects: Do not fill_pool() if pi_blocked_on
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
debugobjects: Do not fillpool() if piblocked_on
On RT enabled kernels, fillpool() ends up calling rtlocklock(), which asserts if current::piblockedon 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::piblockedon into account.
