Local kernel memory corruption via oversized loop bound
Published Sep 18, 2024 · Updated May 11, 2026
Out-of-bounds writes in Linux 4.15 through 6.10.8 AMD display clock handling allow local users to overrun a kernel array. In dcn35_dccg.c, two loops use sizeof(fe_clk_en), 20 bytes, as an element count for the five-entry fe_clk_en array, iterating past its bounds. Reachability requires a local low-privileged context and the affected AMD display path; public sources do not identify the runtime action that triggers the loops or a demonstrated end effect.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
