- Summary
- mm: multi-gen LRU: fix crash during cgroup migration
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
mm: multi-gen LRU: fix crash during cgroup migration
lrugenmigratemm() assumes lrugenaddmm() runs prior to itself. This isn't true for the following scenario:
CPU 1 CPU 2clone() cgroupcanfork() cgroupprocswrite() cgrouppostfork() tasklock() lrugenmigratemm() taskunlock() tasklock() lrugenaddmm() taskunlock()
And when the above happens, kernel crashes because of linked list corruption (mmstruct->lrugen.list).
