EUVD-2026-45794

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...

The vulnerability of the af_unix component in the Linux operating system kernel allows a hacker to trigger a service failure.

The vulnerability of the afunix component in the Linux operating system kernel is related to the simultaneous execution using shared resources with incorrect synchronization. Exploiting this vulnerability can allow an attacker to cause service failures...

CVE-2026-53361

The CVE-2026-53361 vulnerability affects the Linux kernel, specifically af_unix code in unix_gc() where gc_in_progress could be observed as false during scheduling, potentially allowing a sequence where gc_in_progress is not reliably set. The root cause is the race between unix_schedule_gc() and ...

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-2026-53005

A flaw was found in the Linux kernel's afunix component, specifically within its SOCKMAP feature. This vulnerability stems from the kernel's improper handling of Socket Control Message SCM attributes when data is passed to the SOCKMAP layer. This can lead to a use-after-free condition, which may...

CVE-2026-53034

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF and sockmap components, specifically within the afunix socket operations. A race condition occurs during the connection process where a socket's state is updated before its peer is fully assigned. This timing issue can lead to a...
