**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to the `vmalloc` function in the Linux kernel, which may return null when called with ` GFP NOFAIL`. This can cause a kernel panic due to a null pointer dereference. The problem occurs when the `oom-killer` sends a signal to a process, and the `vm area alloc pages` function returns null. To fix this, the `fatal signal pending` check should be removed from `vm area alloc pages` when ` GFP NOFAIL` is set. The issue was discovered during the OPLUS KASAN TEST. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
