postgresql: PostgreSQL: Denial of Service via uncontrolled recursion in SSL/GSS negotiation

A flaw was found in PostgreSQL. Uncontrolled recursion during SSL Secure Sockets Layer and GSS Generic Security Service negotiation allows an attacker to achieve a sustained denial of service. This can be exploited by an attacker with access to a PostgreSQL AFUNIX socket. If SSL and GSS are both...

CVE-2026-7374

A flaw was found in KubeVirt's virt-handler component.

By replacing the console socket with a symlink to...

Astra Linux – Vulnerability in Redis

Redis is an in-memory database that persists data on disk. Upon startup, Redis begins listening on Unix sockets before adjusting its permissions to the configuration provided by the user. If a permissive umask value is used, this can create a race condition that allows another process to establis...

Astra Linux – Vulnerability in WebKit2GTK

In BubblewrapLauncher.cpp in WebKitGTK and WPE WebKit before version 2.34.1, there was a limited bypass of the sandbox mechanism that allowed a sandboxed process to trick host processes into believing that the sandboxed process was not confined by the sandbox. This was achieved by exploiting VFS...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: BPF: Added checks for skisinet and ISICSK in tlsswhasctxtx/rx. With the introduction of support for vsock and Unix sockets in sockmap, tlsswhasctxtx/rx cannot assume that the socket passed in must be of type ISICSK. Sockets of...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: Do not write to msggetinq in the callee. A fix for NULL pointer dereferencing issues. msggetinq is an input field from the caller to the callee. Do not set it in the callee, as the caller may not clear it during struct reuse...

Astra Linux – Vulnerability in Flatpak

Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. In versions prior to 1.10.4 and 1.12.0, Flatpak applications that had direct access to AFUNIX sockets—such as those used by Wayland, Pipewire, or pipewire-pulse—could trick portals and other host-...

Astra Linux – Vulnerability in multipath-tools

In versions of multipath-tools from 0.7.0 to 0.9.x, up to 0.9.2, local users could obtain root access, either alone or in conjunction with CVE-2022-41973. Local users who had access to write to UNIX domain sockets could bypass access controls and manipulate the multipath setup. This could result ...

FreeBSD Security Advisory - FreeBSD-SA-26:22.libcasper
