CVE-2021-46910

CVE-2021-46910 relates to the Linux kernel’s kmap_local(): when CONFIG_DEBUG_KMAP_LOCAL=y, per-CPU fixmap slots are doubled, causing the fixmap region to grow downwards and potentially collide with the virtual DT mapping. The documented impact is a local exploit path leading to kernel instability...
