Description

A flaw was found in the Linux kernel. An unchecked return value in the module_extend_max_pages() function within the module decompression logic can lead to a null pointer dereference. This vulnerability can be triggered if memory allocation fails during module loading, resulting in a kernel oops. This can allow a local attacker to cause a denial of service (DoS) by crashing the system.
