ROS-20260925-73-0173

The vulnerability of the nbdgenlconnect function in the drivers/block/nbd.c module of the Linux kernel’s block devices driver is related to the repeated use of previously freed memory. Exploiting this vulnerability could allow an attacker to cause a service failure...

Astra Linux – Vulnerability in Linux

In the rbd block device driver located in drivers/block/rbd.c within the Linux kernel, up to version 5.8.9, incomplete permission checks were used for accessing rbd devices. This could have been exploited by local attackers to map or unmap rbd block devices, specifically the CID-f44d04e696fe devi...

ROS-20260827-73-0017

The vulnerability of the nullinittagset function in the drivers/block/nullblk/main.c module of the Linux kernel’s block devices driver is related to insufficient validation of input data. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...

CVE-2026-68147

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

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.

CVE-2026-68147 fscrypt: Avoid dynamic allocation in fscrypt_get_devices()

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-2026-68147

Summary: CVE-2026-68147 affects the Linux kernel fscrypt subsystem. When a blk_crypto_key is evicted, the code previously allocated a list of block devices on the heap; allocation failures could lead to premature key free and a use-after-free. The fix switches to an on-stack array to enumerate bl...

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,...
