What is CVE-2026-97941?
This vulnerability in the Linux kernel arises from a race condition in the memory management subsystem, specifically within the slab allocator. The issue occurs because certain assumptions about the state of the slab list can lead to memory corruption when an object is freed while another CPU simultaneously handles memory allocation. A failure in proper locking mechanisms during the manipulation of the slab lists can lead to synchronization issues, resulting in severe system instability, including kernel panics and unexpected behaviors. To mitigate this issue, it is recommended to enhance locking around slab list operations, ensuring that list manipulations are properly serialized.
