CVE-2026-64187

In the Linux kernel, the following vulnerability has been resolved: xfs: fail recovery on a committed log item with no regions If the first op of a transaction is a bare transaction header len == sizeofstruct xfstransheader, xlogrecoveraddtotrans adds an item but no region, leaving it on ritemq...

CVE-2026-63800

A flaw was found in the Linux kernel's parallel Network File System pNFS component. An issue in the pnfsupdatelayout function causes a use-after-free vulnerability due to incorrect ordering of memory management operations. This flaw can be triggered when the system attempts to update a pNFS layou...

CVE-2026-40187 Authenticated RCE via Malicious eTemplate Upload in EGroupware

In egroupware version 26.0 and earlier, an authenticated administrator can achieve OS-level Remote Code Execution RCE by uploading a malicious eTemplate XML file .xet to the VFS /etemplates mount. The Widget::expandname method passes template widget attribute values directly into a PHP eval call...

USN-8570-1: Linux kernel vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - Foo-over-UDP FOU; - ARM64 architecture; - x86 architecture; - Block layer subsystem; - Drivers core; - Null block...

CVE-2026-53397

A flaw was found in the Linux kernel's Network File System Daemon nfsd. This vulnerability occurs during the processing of Access Control List ACL set operations. If a specific decode step fails, a memory leak of a posixacl object occurs. This can lead to resource exhaustion over time, potentiall...

CVE-2026-53394

A flaw was found in the Linux kernel's Network File System NFS version 4.0 NFSv4.0 OPEN implementation. A race condition can occur when two NFSv4.0 OPEN threads with the same owner string attempt to open a file, and a concurrent thread inserts a new unconfirmed owner. This can lead to a memory le...

CVE-2026-53395

A flaw was found in the Linux kernel's Network File System NFS daemon nfsd. A remote attacker can exploit this vulnerability by sending specially crafted NFS CREATE requests that include conflicting Access Control List ACL attributes. This leads to a memory leak, where the system fails to release...

CVE-2026-53399

A use-after-free flaw was found in the Linux kernel's NFS daemon nfsd pNFS layout handling. When nfsd4layoutsetlease fails, the layout stateid that was already published in the client IDR is freed directly, leaving a stale pointer in the IDR. A subsequent IDR traversal, such as statesshow or clie...

CVE-2026-63090

ProFTPD before 1.3.9c and 1.3.10rc3 contains a heap-based buffer overflow vulnerability in the modsftp module that allows authenticated low-privilege attackers to achieve arbitrary code execution by sending crafted SFTP packet fragments exceeding the 16 KB reassembly buffer in the fxp.c component...

CVE-2026-53398

A flaw was found in the Linux kernel's Network File System Daemon NFSD. The nfsd4decodesecinfononame function does not properly initialize a pointer sinexp before processing an incoming data stream. If the data stream is malformed or truncated, the uninitialized pointer can retain stale data from...

CVE-2026-53391

A flaw was found in the Linux kernel's NFSv4/pNFS implementation. The nfs4decodempdsaddr function, responsible for decoding network address information, does not properly handle zero-length raddr opaque data. A malicious or compromised metadata server can exploit this by providing a zero-length...

CVE-2026-64157

A flaw was found in the Linux kernel's network file system netfs component. This vulnerability allows for incorrect handling of data during partial invalidation operations on streaming-write pages. An attacker could potentially exploit this to cause data corruption or unexpected system behavior,...

CVE-2026-64058

A flaw was found in the Linux kernel's network file system netfs component. The netfsreadfolio function fails to wait for ongoing writeback operations to complete. This can lead to the system incorrectly trusting the dirty flag and prematurely cleaning up private data associated with a folio,...

CVE-2026-64156

A flaw was found in the Linux kernel's network file system netfs and AFS Andrew File System components. When a write operation is skipped due to lock contention and a specific writeback control flag WBSYNCNONE, the system may fail to correctly re-mark the inode, which is a data structure that...
