CVE-2026-31447

CVE-2026-31447 affects the Linux kernel ext4, where mounting a filesystem with bigalloc and s_first_data_block != 0 is rejected. The root cause is that this configuration is not supported, leading to a mount-time denial of access (DoS potential). Connected records show patches in Root: Debian 11/...
