Name of the Vulnerable Software and Affected Versions
Linux kernel versions 4.0-rc1 through 5.4.193+
Description
A race condition was found in the Linux kernel's perf event open() function, which can be exploited by an unprivileged user to gain root privileges. The bug allows for the creation of several exploit primitives, such as kernel address information leak and arbitrary execution. This issue is caused by a use-after-free condition in the perf subsystem, which can be used to initiate access to already freed kernel memory.
Recommendations
For Linux kernel versions 4.0-rc1 through 5.4.193+, consider upgrading to a newer version that contains a fix for this issue.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
