CVE-2026-68147

Summary (CVE-2026-68147) In the Linux kernel, the fscrypt subsystem fixed a dynamic allocation pitfall in fscrypt_get_devices(), which gathers the filesystem’s block-device list to apply config/start/evict calls. The vulnerability arose because the device pointers were stored in a dynamically all...

EUVD-2026-55532

In the Linux kernel, the following vulnerability has been resolved: fscrypt: Avoid dynamic allocation in fscryptgetdevices When a blkcryptokey starts being used or is evicted, fs/crypto/ calls fscryptgetdevices to get the filesystem's list of block devices, then iterates over them and calls...

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_...

In the Linux kernel, the following vulnerability has been resolved: super: fix emergency thaw deadlock on frozen block devices dothawallcallback calls bdevthaw while holding sb-sumount exclusively. If the block device was frozen via bdevfreeze dropping the last block layer freeze reference calls...

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,...
