CVE-2024-38543

A flaw was found in the Linux kernel. This vulnerability, located in the lib/test_hmm.c component, arises from improper handling of memory allocation failures within the dmirror_device_evict_chunk() function. Specifically, if kcalloc() returns null due to insufficient physical memory, dereferencing src_pfns or dst_pfns can lead to a null pointer dereference. A local attacker with low privileges could exploit this issue to trigger a denial of service, potentially causing the system to become unresponsive or crash.
