kernel: af_unix: Set gc_in_progress to true in unix_gc()

A flaw was found in the Linux kernel's afunix component. A race condition exists within the unixgc garbage collection function where the gcinprogress flag may not be correctly set. This could lead to unixpeekfpl misinterpreting garbage collection status when handling MSGPEEK operations, potential...

Vulnerability of the unix_gc() component. Igor, MSG_PEEK. Let’s talk about the kernels of the Linux operating system, which allow attackers to trigger a service failure.

Vulnerability of the unixgc component. Igor, MSGPEEK. The kernels of the Linux operating system are related to the swapping of pointers with expired lifetimes. Exploitation of this vulnerability can allow an attacker to cause a service failure...

CVE-2025-13350: Use After Free

Ubuntu Linux 6.8 GA retains the legacy AFUNIX garbage collector but backports upstream commit 8594d9b85c07 "afunix: Don’t call skbget for OOB skb". When orphaned MSGOOB sockets hit unixgc, the garbage collector still calls kfreeskb as if OOB SKBs held two references; on Ubuntu Linux 6.8 Noble...

CVE-2022-50234: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: iouring/afunix: defer registered files gc to iouring release Instead of putting iouring's registered files in unixgc we want it to be done by iouring itself. The trick here is to consider iouring registered files for cycle...

The vulnerability of the unix_gc() function in the net/unix/garbage.c module, which is part of the Linux kernel’s networking functions, allows a attacker to cause a service failure.

The vulnerability of the unixgc function in the net/unix/garbage.c module, which is part of the Linux kernel’s networking functions, is related to security configuration errors. Exploiting this vulnerability could allow an attacker to cause a service failure...
