CVE-2023-2008

A flaw was found in the Linux kernel's udmabuf device driver, within a fault handler. This issue occurs due to the lack of proper validation of user-supplied data, which can result in memory access past the end of an array. This may allow an attacker to escalate privileges and execute arbitrary code in the context of the kernel.
