CVE-2026-53346

CVE-2026-53346 relates to the Linux kernel on arm64 where a rustc bug prevents -Cforce-unwind-tables=y from applying the uwtable annotation to the module, only to individual functions. Consequently, compiler-generated constructors (e.g., asan.module_ctor) lack uwtable metadata. When CONFIG_UNWIND...

CVE-2026-53343

CVE-2026-53343 affects the Linux kernel on ARM when CONFIG_KASAN_VMALLOC and CONFIG_VMAP_STACK are enabled. The vulnerability arises from an unaligned access in the KASAN VMAP stack shadow in __switch_to(), where a prior dummy read used a word load (ldr) against a byte-granular shadow memory. The...
