SUSE CVE-2026-72102

In the Linux kernel, the following vulnerability has been resolved: dmearlycreate: fix freeing used table on dmresume failure If dmresume fails, the kernel attempts to free table with dmtabledestroy, but the table was already instantiated with dmswaptable. This commit skips the call to...

SUSE CVE-2026-72103

In the Linux kernel, the following vulnerability has been resolved: dm: avoid leaking the caller's thread keyring via the table device file The refactoring in commit a28d893eb327 "md: port block device access to file" accidentally causes the caller's thread keyring to be kept alive long beyond th...

SUSE CVE-2026-72101

In the Linux kernel, the following vulnerability has been resolved: dm-integrity: fix leaking uninitialized kernel memory If hash size is less than device's tuple size, dm-integrity is supposed to zero the remaining space. There was a bug in the code that zeroing didn't work. This commit fixes it...

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-2026-74392

A flaw was found in the Linux kernel's device mapper dm component. When iouring with IOPOLL is used on a dm-stripe target, a task can enter a prolonged spinning poll loop. This can lead to an RCU Read-Copy Update CPU stall, causing a Denial of Service DoS for the affected system...

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...

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...

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...

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...

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...
