Description

A flaw was found in the Linux kernel's AMD KFD (Kernel Fusion Driver) component. This buffer overflow vulnerability occurs due to incorrect memory buffer handling during CRIU (Checkpoint/Restore in User-space) operations on SDMA (System Direct Memory Access) queues. A local attacker can exploit this flaw during CRIU restore operations, which can lead to memory corruption in adjacent kernel memory, potentially impacting system stability or leading to further compromise. Additionally, during CRIU checkpoint operations, this vulnerability can result in information disclosure of adjacent kernel memory to userspace.
