linux: A flaw was found in the Linux kernel's udmabuf device driver, within a fault handler
CVE-2023-2008 is fixed in 39 products on 1 platform, first by RHSA-2022:8267, released November 15, 2022. It is not reported as exploited. Patch Radar priority: High.
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.
