Detailsinfo

A vulnerability has been found in Imagination Graphics DDK up to 26.1 RTM2 and classified as very critical. Affected by this vulnerability is an unknown function of the component Fence Synchronization Checkpoints. The manipulation with an unknown input leads to a stack-based overflow vulnerability. The CWE definition for the vulnerability is CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Software installed and run as a non-privileged user may conduct improper GPU system calls causing a stack overflow in the kernel. The overflow occurs when processing resolved Linux/Android fence synchronization checkpoints, while user checkpoints are excluded from the stack array. Successful exploitation can cause kernel memory corruption and typically results in a denial-of-service condition through a kernel crash. The code vulnerability is a buffer write beyond the allocated array on the stack caused by copying excessive data from an internal buffer.

It is possible to read the advisory at imaginationtech.com. This vulnerability is known as CVE-2026-65584 since 07/22/2026. The exploitation appears to be easy. Attacking locally is a requirement. The technical details are unknown and an exploit is not publicly available. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 10/30/2026).
