CVE-2026-46005

A flaw was found in the Linux kernel's xfs filesystem. This resource leak occurs in the xfsallocbuftarg function's error path, where a DAX Direct Access device reference is not properly dropped. An attacker could potentially exploit this flaw to cause resource exhaustion, leading to a Denial of...

Astra Linux – Vulnerability in Linux, Linux 5.10

A data leak flaw was discovered in the way of the XFSIOCALLOCSP IOCTL in the XFS filesystem, which allows for an increase in file sizes when the size is unaligned. A local attacker could exploit this flaw to leak data from the XFS filesystem that would otherwise be inaccessible to them...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: xfs: Do not perform irele after failing to perform iget in xfsattrirecoverwork. xlogrecoveryiget never sets @ip to a valid pointer if it returns an error; therefore, this irele will cause a dangling pointer. This issue has bee...

Astra Linux – Vulnerability in Linux, Linux 5.10

A vulnerability was discovered in the fs/inode.c:inodeinitowner function logic of the Linux kernel. This vulnerability allows local users to create files for the XFS file system with unintended group ownership, along with group execution and SGID permission bits set. This occurs in a scenario whe...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: fsdax: Force the dirty mark to be cleared if CoW is used XFS allows CoW on non-shared extents to combat fragmentation1. The old non-shared extent can be rewritten before use; its dax entry is marked as “dirty”. This results in a...

CVE-2026-43365

A flaw was found in the Linux kernel's XFS filesystem. This vulnerability arises when the filesystem superblock, which contains critical metadata, does not correctly specify a log stripe unit. This can lead to undersized log roundoff values, causing log corruption. A local attacker could...

CVE-2026-43153

A flaw was found in the Linux kernel's XFS filesystem. The xfsattrleafhasname function has a problematic calling convention that can lead to incorrect buffer handling. This issue can result in the use of already released memory buffers, potentially causing memory corruption or system instability....

CVE-2026-43153

In the Linux kernel, the following vulnerability has been resolved: xfs: remove xfsattrleafhasname The calling convention of xfsattrleafhasname is problematic, because it returns a NULL buffer when xfsattr3leafread fails, a valid buffer when xfsattr3leaflookupint returns -ENOATTR or -EEXIST, and ...

CVE-2026-43187

In the Linux kernel, the following vulnerability has been resolved: xfs: delete attr leaf freemap entries when empty Back in commit 2a2b5932db6758 "xfs: fix attr leaf header freemap.size underflow", Brian Foster observed that it's possible for a small freemap at the end of the end of the xattr...

CVE-2026-43063

A flaw was found in the Linux kernel's XFS filesystem. When recovering attributes, if the xlogrecoveryiget function fails to obtain a valid pointer, a subsequent irele operation attempts to release an invalid memory address. This dangling pointer issue can be exploited by a local attacker,...

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 improper cleanup of freemap entries in xfs attribute leaf nodes. This issue may lead to underflow...

PT-2026-37066

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw exists in the XFS file system where the xfs attri recover work function incorrectly calls irele after a failure in iget. Because xlog recovery iget functions do not set the @ip...

CVE-2026-43053

A flaw was found in the Linux kernel's XFS filesystem. During the inactivation of inodes with extended attributes, a specific timing window exists where a log shutdown can occur after some data blocks are invalidated but before the attribute map is fully truncated. This can lead to inconsistencie...

CVE-2026-31556

A flaw was found in the Linux kernel's XFS filesystem component. During quota scrubbing, the xchkquotaitem function could exit prematurely without releasing a critical lock. This can result in lock leaks or deadlocks in subsequent quota operations, potentially leading to system instability or a...

CVE-2026-31556

In the Linux kernel, the following vulnerability has been resolved: xfs: scrub: unlock dquot before early return in quota scrub xchkquotaitem can return early after calling xchkfblockprocesserror. When that helper returns false, the function returned immediately without dropping dq-qqlock, which...

CVE-2026-31455

A flaw was found in the Linux kernel's XFS file system. During the unmount process, the system attempts to flush data while background cleanup and inode garbage collection inodegc operations are still active. This improper synchronization can lead to data integrity issues or system instability, a...

CVE-2026-31453

A flaw was found in the Linux kernel's XFS filesystem. This vulnerability arises when log items are accessed after their memory has been freed, specifically during certain push callbacks if the Allocation Information List AIL lock is released. This memory corruption can lead to a system crash,...

CVE-2026-31454 xfs: save ailp before dropping the AIL lock in push callbacks

In the Linux kernel, the following vulnerability has been resolved: xfs: save ailp before dropping the AIL lock in push callbacks In xfsinodeitempush and xfsqmdquotlogitempush, the AIL lock is dropped to perform buffer IO. Once the cluster buffer no longer protects the log item from reclaim, the...

USN-8177-1 linux, linux-realtime vulnerabilities

Josh Eads, Kristoffer Janke, Eduardo Vela Nava, Tavis Ormandy, and Matteo Rizzo discovered that some AMD Zen processors did not properly verify the signature of CPU microcode. This flaw is known as EntrySign. A privileged attacker could possibly use this issue to cause load malicious CPU microcod...
