kernel: gfs2: add some missing log locking

A flaw was found in the Linux kernel's Global File System 2 GFS2 component. The gfs2logd function, responsible for log flushing, calls several log flushing functions without holding the required lock. This omission allows concurrent transactions to access shared resources without proper exclusion...

kernel: gfs2: Fix slab-use-after-free in qd_put

A flaw was found in the Linux kernel's GFS2 file system. During filesystem shutdown, quota data objects were freed without being properly removed from the Least Recently Used LRU list. This oversight could lead to a use-after-free vulnerability, where the system attempts to access memory that has...

kernel: gfs2: Fix use-after-free in iomap inline data write path

A flaw was found in the Linux kernel's GFS2 filesystem. This memory corruption vulnerability, a use-after-free, occurs in the iomap inline data write path. The issue arises because a data buffer is released prematurely while still being referenced, leading to a write to freed memory. This could...

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

An update for kernel is now available for Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support and Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerabilit...

RockyLinux 8 : kernel-rt (RLSA-2026:75746)

The remote RockyLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2026:75746 advisory. kernel: Linux kernel: Use-after-free in xc5000 tuner driver due to race condition CVE-2025-39994 kernel: gfs2: Fix unlikely race in gdlmputlock...

kernel: gfs2: Fix unlikely race in gdlm_put_lock

A flaw was found in the Linux kernel’s Global File System 2 implementation affecting distributed lock manager DLM handling in the gdlmputlock function. During an unmount operation, if the DFLUNMOUNT flag is set but the lockspace has not yet been fully released, remote callbacks gdlmast or gdlmbas...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: gfs2: Fixed a use-after-free in the iomap inline data write path The inline data buffer head dibh is released prematurely in gfs2iomapbegin via releasemetapath, while iomap-inlinedata still points to dibh-bdata. This causes a...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: gfs2: The use-of-free variable issue in gfs2glockshrinkscan has been fixed. The GLFLRU flag is checked under lrulock in gfs2glockremovefromlru, to remove a glock from the lru list in gfs2glockput. During the shrink scan process,...

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

In the Linux kernel, the following vulnerability has been resolved: gfs2: Fixed possible data races in gfs2showoptions Some fields such as gtlogdsecs of the struct gfs2tune are accessed without holding the lock gtspin in gfs2showoptions: val = sdp-sdtune.gtlogdsecs; if val != 30 seqprintfs,...

SUSE CVE-2026-97520

In the Linux kernel, the following vulnerability has been resolved: gfs2: move quotainit qc iterator increment Move qc++ from the loop body into the for-loop increment expression in gfs2quotainit. This keeps iterator progression explicit and avoids mixing pointer advance with duplicate-slot...

CVE-2026-97521

A flaw was found in the Linux kernel's GFS2 Global File System 2 file system, which can lead to a Denial of Service DoS. In real-time kernel configurations, the quota initialization routine improperly invokes a sleeping function while holding an atomic lock. A local user capable of triggering GFS...

ROS-20260928-73-0054

The vulnerability of the gdlmputlock function in the fs/gfs2/lockdlm.c file of the GFS2 file system in the Linux operating system is related to the pointer manipulation. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of the...
