UBUNTU-CVE-2022-49055

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Check for potential null return of kmallocarray As the kmallocarray may return null, the 'eventwaitersi.wait' would lead to null-pointer dereference. Therefore, it is better to check the return value of kmallocarray t...
