About this tag
CVE-2022-48893 is a Linux kernel vulnerability in the Intel i915 DRM driver that affects systems using Intel integrated graphics. The flaw occurs when driver initialization aborts during GT/engine discovery, leaving engine structures partially initialized with unset cleanup hooks. This can lead to leaked shared resources, causing resource exhaustion or system instability. The vulnerability is classified as an availability and reliability issue, not a remote code execution vector. The fix performs defensive cleanup on early failures to prevent partial initialization. This tag covers discussions about the CVE, its impact on Intel graphics driver reliability, and the kernel patch that addresses the issue.
