CVE-2026-53796

A time-of-check to time-of-use TOCTOU race condition in rsync's non-daemon receiver allows a local attacker to compromise data integrity. By substituting a symbolic link for a destination path component during directory processing, an attacker can redirect file writes to unintended locations...

CVE-2026-53799

A symlink race condition in rsync allows a local attacker to achieve privilege escalation. By substituting a symlink at a predictable destination path between a file write and the application of access control lists ACLs or extended attributes xattrs, an attacker can redirect these permissions to...

USN-8726-1 linux, linux-aws, linux-aws-7.0, linux-gcp, linux-gke, linux-hwe-7.0, linux-realtime vulnerabilities

It was discovered that some Arm processors could complete a broadcast translation lookaside buffer TLB invalidation before memory writes made through the invalidated translation were globally observed. A local attacker could possibly use this to write to memory after permission to do so had been...

USN-8726-1: Linux kernel vulnerabilities

It was discovered that some Arm processors could complete a broadcast translation lookaside buffer TLB invalidation before memory writes made through the invalidated translation were globally observed. A local attacker could possibly use this to write to memory after permission to do so had been...

PT-2026-86845

A flaw was found in GLib2. When g file replace is used with G FILE CREATE REPLACE DESTINATION and creating the .goutputstream-XXXXXX temporary file fails, the library unlinks the destination and recreates it without exclusive creation or symlink protection. A local attacker who can write to the...

CVE-2026-86469: Improper Link Resolution Before File Access

A flaw was found in GLib2. When gfilereplace is used with GFILECREATEREPLACEDESTINATION and creating the .goutputstream-XXXXXX temporary file fails, the library unlinks the destination and recreates it without exclusive creation or symlink protection. A local attacker who can write to the...

Linux Distros Unpatched Vulnerability : CVE-2026-86469

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A flaw was found in GLib2. When gfilereplace is used with GFILECREATEREPLACEDESTINATION and creating the .goutputstream-XXXXXX temporary file fails, the library...

libxml2: libxml2: Arbitrary code execution via stack-based buffer overflow in xmlSnprintfElements

A flaw was found in libxml2. A local attacker could exploit a stack-based buffer overflow in the xmlSnprintfElements function to achieve arbitrary code execution. This vulnerability in a fundamental system library could lead to significant system compromise if successfully exploited...

libxml2: libxml2: Denial of Service due to NULL pointer dereference in xmlRegNewParserCtxt

A NULL pointer dereference in libxml2's xmlRegNewParserCtxt function allows a local attacker to cause a denial of service DoS. The flaw occurs when strlen is called on an unverified pointer following a failed xmlStrdup memory allocation, resulting in a process crash...

libxml2: libxml2: Heap-based buffer overflow in xmlXPtrEval due to xpointer length saturation

A flaw in libxml2's xmlXPtrEvalXPtrPart function allows a local attacker to cause a heap-based buffer overflow. An integer overflow while processing an oversized xpointer expression leads to incorrect memory allocation and an out-of-bounds write, potentially resulting in information disclosure,...

OESA-2026-3647 sssd security update

Provides a set of daemons to manage access to remote directories and authentication mechanisms. It provides an NSS and PAM interface toward the system and a pluggable back end system to connect to multiple different account sources. It is also the basis to provide client auditing and policy...

OESA-2026-3614 popt security update

The popt library exists essentially for parsing command line options. Some specific advantages of popt are no global variables allowing multiple passes in parsing argv, parsing an arbitrary array of argv-style elements allowing parsing of command-line-strings from any source, a standard method of...

OESA-2026-3600 tar security update

GNU Tar provides the ability to create tar archives, as well as various other kinds of manipulation. For example, you can use Tar on previously created archives to extract files, to store additional files, or to update or list files which were already stored. Security Fixes: A TOCTOU Time-of-Chec...
