CVE-2023-53254

CVE-2023-53254 is a Linux kernel vulnerability related to the cacheinfo shared_cpu_map. The issue occurs when the kernel checks that caches with the same index are shared, which can trigger slab-out-of-bounds access if CPUs have different cache hierarchies. A second problem is a mismatched shared...
