CVE-2026-31654

CVE-2026-31654 affects the Linux kernel mm/vma path for mmap-backed shared mappings (notably /dev/zero). The root cause was a memory leak: when __mmap_new_vma() fails after shmem_zero_setup_desc() allocates a replacement shmem file, that new file isn’t released in the error path, leaving an unref...
