Linux Distros Unpatched Vulnerability : CVE-2026-72183

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - landlock: Fix LANDLOCKSCOPESIGNAL bypass on the SIGIO path LANDLOCKSCOPESIGNAL must prevent a sandboxed process from signaling processes outside its Landlock...

CVE-2026-72183

A flaw was found in the Linux kernel's Landlock security module. A sandboxed process can bypass the intended signal isolation provided by LANDLOCKSCOPESIGNAL. By manipulating file descriptors with specific fcntl calls and asynchronous I/O SIGIO delivery, a local attacker can send signals, such as...

CVE-2026-72183

CVE-2026-72183 concerns a Linux kernel LANDLOCK bypass on the SIGIO path. The vulnerability allowed a sandboxed process that owns a file/socket to arm fcntl(F_SETOWN), F_SETSIG and O_ASYNC so that an I/O event would deliver a chosen signal to the entire process group, potentially affecting non-sa...

FreeBSD -- pts(4) write-after-free

Problem Description: The code which handles a close2 of a descriptor created by posixopenpt2 fails to undo the configuration which causes SIGIO to be raised. This bug can lead to a write-after-free of kernel memory. Impact: The bug permits malicious code to trigger a write-after-free, which may b...
