In the Linux kernel, the following vulnerability has been resolved: dm thin: Make getfirstthin use rcu-safe list first function. The documentation in rculist.h explains the absence of listemptyrcu and warns programmers against relying on a sequence of listempty - listfirst in RCU-safe code. This ...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: dm: Fix NULL pointer dereferencing in dmsuspend. There is a race condition between the suspension of the dm device and the loading of data into the table, which can lead to a NULL pointer dereferencing. This issue occurs when the...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: dm integrity: Memory corruption occurs when tagsize is less than digestsize. It is possible to configure dm-integrity in such a way that the tagsize parameter is smaller than the actual digestsize. In this case, a portion of the...

Astra Linux – Vulnerability found in Linux 5.15, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: - dm clone: Fixed a UAF Use-after-Free in clonedtr. - Dmclone also has the same UAF issue when dmresume and dmdestroy are executed concurrently. Therefore, the timer is canceled again in clonedtr...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: dm rq: Fixed a double-free of blkmqtagset in the dev remove operation after the table load fails. When loading a device-mapper table for a request-based mapped device, and the allocation/initialization of the blkmqtagset for the...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: dm: Clearing the clone request’s bio pointer when the last cloned bio is freed It was observed that stale values of rq-bio could lead to double initialization of cloned bios in request-based device-mapper targets, resulting in...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: dm-pcache: Rejects option groups without values. The pcache target parses optional arguments as name/value pairs. A table that advertises one optional argument and provides only a recognized option name, such as “cachemode”, will...

CVE-2026-72316

A flaw was found in the Linux kernel's device mapper dm era target. When the metadataopen function fails to allocate memory, it returns a NULL pointer. The calling function, eractr, does not correctly validate this return, leading to a NULL pointer dereference when the metadata is accessed. This...

CVE-2026-72104

A flaw was found in the Linux kernel's device-mapper pcache target. A local user could trigger a system crash by providing a malformed table to the pcache target. This occurs because the system attempts to process an option without a value, leading to a critical error. The primary impact is a...

Moderate: Red Hat Security Advisory: kernel security, bug fix, and enhancement update

An update for kernel is now available for Red Hat Enterprise Linux 9.6 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for...

kernel: dm log: fix out-of-bounds write due to region_count overflow

A flaw was found in the Linux kernel's device-mapper log dm log component. A local attacker could exploit an integer overflow vulnerability where a 64-bit value is truncated to 32 bits, leading to undersized memory allocations. This allows for out-of-bounds writes to kernel memory during log...

Linux Distros Unpatched Vulnerability : CVE-2026-72102

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - dmearlycreate: fix freeing used table on dmresume failure If dmresume fails, the kernel attempts to free table with dmtabledestroy, but the table was already...

CVE-2026-72108

A flaw was found in the Linux kernel's device-mapper dm thin metadata component. When operations involving metadata snapshots, such as reserving or releasing a snapshot, encounter a commit failure, the system can write an inconsistent 'heldroot' to disk. This can lead to metadata corruption withi...

CVE-2026-72107

A flaw was found in the Linux kernel's device-mapper dm-era component. This vulnerability arises from an incorrect calculation of writeset blocks, which can lead to an out-of-bounds memory access. An attacker could potentially exploit this to cause a denial of service or other undefined behavior...

CVE-2026-72103

A flaw was found in the Linux kernel's device-mapper dm component. A refactoring error caused the caller's thread keyring, which can contain sensitive data like LUKS volume keys, to persist in memory longer than intended. This issue allows a local attacker with administrative privileges to recove...

CVE-2026-72102

A flaw was found in the Linux kernel's device mapper DM subsystem. During certain resume operations, the kernel might attempt to free a memory table that has already been released. This error, known as a double-free vulnerability, can lead to memory corruption. A successful exploit could result i...
