NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64k-debug-devel-matched package and not the kernel-64k-debug-devel-matched package as distributed by RHEL.

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

drivers/md/md-bitmap: check the return value of md_bitmap_get_counter()

Check the return value of md_bitmap_get_counter() in case it returns NULL pointer, which will result in a null pointer dereference.

v2: update the check to include other dereference
