摘要:
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: NULL-check BO's backing store when determining GFX12 PTE flags
PRT BOs may not have any backing store, so bo->tbo.resource will be
NULL. Check for that before dereferencing.
(cherry picked from commit 3e3fcd29b505cebed659311337ea03b7698767fc)
安全等级: Low
公告ID: KylinSec-SA-2025-2364
发布日期: 2025年4月20日
关联CVE: CVE-2025-21990
在Linux内核中,以下漏洞已被修复:
drm/amdgpu:在确定GFX12 PTE标志时检查BO的backing store是否为NULL
PRT BO可能没有任何backing store,因此bo->tbo.resource将为NULL。在解引用前需要检查该值。
