Overview

Affected versions of this package are vulnerable to Buffer Overflow via the cxlctl_get_feature function. An attacker can cause memory corruption and potentially achieve arbitrary read or write in kernel memory by supplying a crafted value for the count parameter that exceeds the allocated output buffer, leading to a heap out-of-bounds write when processing mailbox payloads through device ioctl operations.

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
