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...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: afunix: Obtaining userns from inskb in unixdiaggetexact. Wei Chen reported a NULL dereference in skuserns 01. Paolo identified the root cause: in unixdiaggetexact, the newly allocated skb does not have sk.2 We must obtain the...

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...

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 – 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 found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: afunix: Clearing stale u-oobskb. Syzkaller began reporting a deadlock of unixgclock after the commit 4090fa373f0. However, this only reveals the bug that had been present since the commit 314001f0bf92 “afunix: Adding OOB support”...

CVE-2026-43016

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter sockmap component. This vulnerability, a use-after-free, occurs due to improper management of AFUNIX socket objects within the skpsockverdictdataready function. A local attacker could exploit this issue by sending specially crafted...

CVE-2026-31673

A flaw was found in the Linux kernel. A race condition in the afunix component allows a local attacker to cause unstable Virtual File System VFS data when UNIXDIAGVFS data is handled. This occurs because inode and device numbers are read without consistently holding the unixstatelock, while u-pat...
