CVE-2026-68132

CVE-2026-68132 concerns the Linux kernel thaw deadlock involving frozen block devices. The root cause is do_thaw_all_callback() calling bdev_thaw() while holding sb->s_umount, which can lead to a deadlock when a block device frozen via bdev_freeze() drops the last freeze reference and fs_bdev_...

CVE-2026-64326

A flaw was found in the Linux kernel's block device handling. When a block device is unexpectedly removed, the bdevmarkdead function can unconditionally attempt to synchronize the device, even if it is no longer present. This can lead to a system hang, effectively causing a Denial of Service DoS,...

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...
