Description
A flaw was found in the Linux kernel's drm/xe/sync subsystem. When processing synchronization entries, the xe_sync_entry_parse() function may fail to properly clean up partially initialized resources. This improper handling of error paths can lead to a resource leak. A local attacker could potentially exploit this to cause resource exhaustion, resulting in a Denial of Service (DoS).
Statement
This Moderate flaw in the Linux kernel's drm/xe/sync subsystem could lead to a denial of service. The vulnerability arises from incomplete resource cleanup during synchronization entry parsing, potentially causing resource exhaustion. Exploitation requires local access to the system.
