Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

A NULL pointer dereference issue was discovered in the gfs2 file system within the Linux kernel. This issue occurs in corrupted gfs2 file systems when the evict code attempts to reference the journal descriptor structure after it has been freed and set to NULL. A privileged local user could explo...

SUSE CVE-2026-45861

In the Linux kernel, the following vulnerability has been resolved: gfs2: Fix slab-use-after-free in qdput Commit a475c5dd16e5 "gfs2: Free quota data objects synchronously" started freeing quota data objects during filesystem shutdown instead of putting them back onto the LRU list, but it failed ...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the gfs2 module failing to remove quota data objects from the LRU list in the qdput function. Thi...

EUVD-2025-201217

In the Linux kernel, the following vulnerability has been resolved: gfs2: Fix unlikely race in gdlmputlock In gdlmputlock, there is a small window of time in which the DFLUNMOUNT flag has been set but the lockspace hasn't been released, yet. In that window, dlm may still call gdlmast and gdlmbast...

DEBIAN-CVE-2025-38710

In the Linux kernel, the following vulnerability has been resolved: gfs2: Validate idepth for exhash directories A fuzzer test introduced corruption that ends up with a depth of 0 in direread, causing an undefined shift by 32 at: index = hash 32 - dip-idepth; As calculated in an open-coded way in...

CVE-2025-38659

In the Linux kernel, the following vulnerability has been resolved: gfs2: No more self recovery When a node withdraws and it turns out that it is the only node that has the filesystem mounted, gfs2 currently tries to replay the local journal to bring the filesystem back into a consistent state. N...

SUSE CVE-2022-49769

In the Linux kernel, the following vulnerability has been resolved: gfs2: Check sbbsizeshift after reading superblock Fuzzers like to scribble over sbbsizeshift but in reality it's very unlikely that this field would be corrupted on its own. Nevertheless it should be checked to avoid the...

kernel: gfs2: Fix potential glock use-after-free on unmount

A vulnerability was found in the Linux kernel within the gfs2 component, where potential use-after-free issues could occur on unmount. When DLM lockspaces are released with remaining locks, callbacks for asynchronous lock contention may access freed objects, causing unexpected behavior...

SUSE CVE-2010-2525

A flaw was discovered in gfs2 file system's handling of acls access control lists. An unprivileged local attacker could exploit this flaw to gain access or execute any file stored in the gfs2 file system...

UBUNTU-CVE-2023-52448

In the Linux kernel, the following vulnerability has been resolved: gfs2: Fix kernel NULL pointer dereference in gfs2rgrpdump Syzkaller has reported a NULL pointer dereference when accessing rgd-rdrgl in gfs2rgrpdump. This can happen when creating rgd-rdgl fails in readrindexentry. Add a NULL...

kernel: gfs2: NULL pointer dereference in gfs2_evict_inode()

A NULL pointer dereference flaw was found in the gfs2 file system in the Linux kernel. This issue occurs on corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it has been freed and set to NULL. This flaw allows a privileged local user to cause ...
