Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1
In the Linux kernel, the following vulnerabilities have been resolved: afunix: Fixed a data race around unixtotinflight. unixtotinflight is updated under spinlockunixgclock, but unixreleasesock reads it without locking. We will use READONCE for unixtotinflight...
Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1
A use-after-free vulnerability in the Linux kernel’s afunix component can be exploited to achieve local privilege escalation. The unixstreamsendpage function attempts to add data to the last skb in the peer’s recv queue without locking the queue. This creates a race condition where...
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-...

Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent has a heap out-of-bounds write in buffereventsock.c when buffereventsocketsetconnaddress copies a kernel-supplied AFUNIX peer address into buffereventprivate.connaddress. Release builds compiled with NDEBUG disab...
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...

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Netty is an asynchronous, event-driven network application framework. In versions prior to 4.1.136.Final and 4.2.16.Final, Netty's HAProxy encoder...
CRLF Injection
Overview Affected versions of this package are vulnerable to CRLF Injection via the encodeV1. An attacker can inject arbitrary CRLF sequences into AFUNIX addresses by supplying specially crafted input, resulting in the creation of multiple PROXY protocol header lines. This can lead to client IP...

SUSE CVE-2026-64109
In the Linux kernel, the following vulnerability has been resolved: afunix: Fix UAF read of tail-len in unixstreamdatawait unixstreamdatawait does skbpeektail&sk-skreceivequeue without holding any lock that prevents SKBs on that queue from being dequeued and freed. This has been the case since...
CVE-2026-64109
CVE-2026-64109 describes a Use-After-Free in the Linux kernel af_unix unix_stream_data_wait() due to peeking tail of the receive queue without proper locking, allowing a race between threads to free a skb while it is referenced. The issue arises because tail is compared to last after a race where...
