CVE-2024-41055

Kernel crash via unchecked sparsemem usage pointer

Published Jul 29, 2024 · Updated May 23, 2026

NULL pointer dereference in Linux kernel memory management allows local users to crash the system during memory section deactivation. The pfn_section_valid() function reads ms->usage once but dereferences the result without first checking whether concurrent section_deactivate() cleared the pointer. Low-privileged local access and a successful race are required, and the bounded consequence is an availability-only kernel crash.
