Details

In the Linux kernel, the following vulnerability has been resolved:

mm/vmalloc: fix vmalloc which may return null if called with _GFPNOFAIL

commit a421ef303008 ("mm: allow !GFPKERNEL allocations for kvmalloc") includes support for _GFP_NOFAIL, but it presents a conflict with commit dd544141b9eb ("vmalloc: back off when the current task is OOM-killed"). A possible scenario is as follows:

process-a _vmallocnoderange(GFPKERNEL | _GFPNOFAIL) _vmallocareanode() vmareaallocpages() --> oom-killer send SIGKILL to process-a if (fatalsignalpending(current)) break; --> return NULL;

To fix this, do not check fatalsignalpending() in vmareaallocpages() if _GFP_NOFAIL set.

This issue occurred during OPLUS KASAN TEST. Below is part of the log -> oom-killer sends signal to process [65731.222840] [ T1308] oom-kill:constraint=CONSTRAINTNONE,nodemask=(null),cpuset=/,memsallowed=0,globaloom,taskmemcg=/apps/uid_10198,task=gs.intelligence,pid=32454,uid=10198
