Overview
Affected versions of this package are vulnerable to Information Exposure in the ptep_clear_flush process. An attacker can gain unauthorized access to sensitive memory contents and cause arbitrary memory corruption by exploiting stale cache lines that are not properly flushed during page table entry updates, leading to potential privilege escalation, data disclosure, and system instability.
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
