CVE-2022-2959

A race condition was found in the Linux kernel's watch queue due to a missing lock in piperesizering. The specific flaw exists within the handling of pipe buffers. The issue results from the lack of proper locking when performing operations on an object. This flaw allows a local user to crash the...

Linux Kernel Watch Queue Race Condition Privilege Escalation Vulnerability

This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of pipe...

CVE-2022-2959

A race condition was found in the Linux kernel's watch queue due to a missing lock in the piperesizering. The race condition occurs when a thread uses ioctlIOCWATCHQUEUESETSIZE to resize the pipe buffer and free the old pipe buffer, while another thread uses keyctl to trigger a notification in th...
