CVE-2026-63881
7.8
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: fix a vulnerability of integer overflow in kfd debugger
get_queue_ids() computes array_size = num_queues * sizeof(uint32_t), which could overflow on 32-bit size_t build. using array_size() instead, it saturates to SIZE_MAX on overflow.
(cherry picked from commit 2d57a0475f085c08b49312dfd8edcb461845f285)
