- Summary
- um: init cpu_tasks[] earlier
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
um: init cpu_tasks[] earlier
This is currently done in umlfinishsetup(), but e.g. with KCOV enabled we'll crash because some init code can call into e.g. memparse(), which has coverage annotations, and then the checks in checkkcov_mode() crash because current is NULL.
Simply initialize the cpu_tasks[] array statically, which fixes the crash. For the later SMP work, it seems to have not really caused any problems yet, but initialize all of the entries anyway.
