Overview

Affected versions of this package are vulnerable to NULL Pointer Dereference in the push_rt_task process. An attacker can cause kernel memory disclosure, arbitrary kernel memory writes, and full system crashes by exploiting a race condition during real-time task migration between CPU runqueues, leading to corruption of scheduler data structures and dereferencing of invalid pointers.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
