SUSE CVE-2026-31437

In the Linux kernel, the following vulnerability has been resolved: netfs: Fix NULL pointer dereference in netfsunbufferedwrite on retry When a write subrequest is marked NETFSSREQNEEDRETRY, the retry path in netfsunbufferedwrite unconditionally calls stream-preparewrite without checking if it is...

SUSE CVE-2026-31453

In the Linux kernel, the following vulnerability has been resolved: xfs: avoid dereferencing log items after push callbacks After xfsaildpushitem calls ioppush, the log item may have been freed if the AIL lock was dropped during the push. Background inode reclaim or the dquot shrinker can free th...

SUSE CVE-2026-31454

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...

SUSE CVE-2026-31455

In the Linux kernel, the following vulnerability has been resolved: xfs: stop reclaim before pushing AIL during unmount The unmount sequence in xfsunmountflushinodes pushed the AIL while background reclaim and inodegc are still running. This is broken independently of any use-after-free issues -...

CVE-2026-41179

Rclone is a command-line program to sync files and directories to and from different cloud storage providers. Starting in version 1.48.0 and prior to version 1.73.5, the RC endpoint operations/fsinfo is exposed without AuthRequired: true and accepts attacker-controlled fs input. Because rc.GetFs...

Azure Linux 3.0 Security Update: CBL-Mariner Releases (CVE-2026-40706)

The version of CBL-Mariner Releases installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2026-40706 advisory. - In NTFS-3G 2022.10.3 before 2026.2.25, a heap buffer overflow exists in...

Luanti 代码注入漏洞

Luanti is an open-source voxel game engine developed by Luanti itself, supporting mods and game creation. Versions of Luanti from 5.0.0 to 5.15.2 had a code injection vulnerability. This vulnerability stemmed from the ability of malicious mods to escape the sandbox Lua environment, potentially...

USN-8201-1: Linux kernel (Azure) vulnerabilities

Qualys discovered that several vulnerabilities existed in the AppArmor Linux kernel Security Module LSM. An unprivileged local attacker could use these issues to load, replace, and remove arbitrary AppArmor profiles causing denial of service, exposure of sensitive information kernel memory, local...

uutils coreutils has an Unchecked Return Value Issue

The dd utility in uutils coreutils suppresses errors during file truncation operations by unconditionally calling Result::ok on truncation attempts. While intended to mimic GNU behavior for special files like /dev/null, the uutils implementation also hides failures on regular files and directorie...

CVE-2026-31454

A flaw was found in the Linux kernel's XFS file system. This vulnerability occurs when the system incorrectly handles memory, specifically when a critical lock, known as the Address Index List AIL lock, is released too early during certain operations. This premature release can cause a piece of...

EUVD-2026-24793

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...

CVE-2026-31454

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...

CVE-2026-31449 ext4: validate p_idx bounds in ext4_ext_correct_indexes

In the Linux kernel, the following vulnerability has been resolved: ext4: validate pidx bounds in ext4extcorrectindexes ext4extcorrectindexes walks up the extent tree correcting index entries when the first extent in a leaf is modified. Before accessing pathk.pidx-eiblock, there is no validation...

TL-RL-FusionNet: An Adaptive and Efficient Reinforcement Learning-Driven Transfer Learning Framework for Detecting Evolving Ransomware Threats

Modern ransomware exhibits polymorphic and evasive behaviors by frequently modifying execution patterns to evade detection. This dynamic nature disrupts feature spaces and limits the effectiveness of static or predefined models. To address this challenge, we propose TL-RL-FusionNet, a reinforceme...
