CVE-2024-53128

Kernel warning via tagged-pointer stack misclassification

Published Dec 4, 2024 · Updated May 11, 2026

Incorrect stack-object detection in Linux allows local users to trigger a kernel warning through tagged KASAN pointers. The object_is_on_stack function compares a tagged object pointer with an untagged stack address instead of resetting the tag first. Reachability requires CONFIG_KASAN_SW_TAGS and CONFIG_KASAN_STACK, while the reported warning also requires CONFIG_DEBUG_OBJECTS.
