Description

A flaw was found in the Linux kernel's AMD KFD (Kernel Fusion Driver) debugger component. The get_queue_ids() function, responsible for handling queue identifiers, contains an integer overflow vulnerability. This occurs when calculating the size of an array, where a malicious local user could provide a large number of queues, causing the size calculation to wrap around on 32-bit systems. This could lead to a heap buffer overflow, potentially resulting in a denial of service or, in certain scenarios, privilege escalation.
