CVE-2026-63810

In CVE-2026-63810, the Linux kernel fixed a vulnerability in the block subsystem by unregistering the bdev pseudo-filesystem to prevent userspace from mounting it. The issue arose because move_mount() could use inode_operations pointers that were always zero for this filesystem, enabling a NULL p...
