Linux Distros Unpatched Vulnerability : CVE-2026-43016
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - bpf: sockmap: Fix use-after-free of sk-sksocket in skpsockverdictdataready. syzbot reported use- after-free of AFUNIX socket's sk-sksocket in...
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...
CVE-2026-31673 af_unix: read UNIX_DIAG_VFS data under unix_state_lock
In the Linux kernel, the following vulnerability has been resolved: afunix: read UNIXDIAGVFS data under unixstatelock Exact UNIX diag lookups hold a reference to the socket, but not to u-path. Meanwhile, unixreleasesock clears u-path under unixstatelock and drops the path reference after unlockin...

Linux Kernel Security Vulnerabilities
The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the reading of UNIXDIAGVFS data in afunix without holding a lock. This could lead to accessing...
