Linux Kernel Null Pointer Dereference Vulnerability in Development Tools

CVE-2026-97519

What is CVE-2026-97519?

A vulnerability has been identified in the Linux Kernel related to null pointer dereferencing in the devcoredump cleanup process. Specifically, when the snapshot is not fully populated, it may lead to a crash if not properly handled. The function xe_devcoredump_snapshot_free() could encounter a situation where its parameter ss->gt is NULL, raising concerns during cleanup actions. To mitigate this vulnerability, safeguards are introduced to check for null values before proceeding with operations that depend on those pointers, ensuring system integrity and stability.
