In the Linux kernel, the following vulnerability has been resolved: accel/ivpu: Fix page fault in ivpu_bo_unbind_all_bos_from_context() Don't add BO… (CVE-2025-68730)
A high-severity vulnerability in the Linux kernel's ivpu driver was resolved. The issue involved a page fault caused by improper handling of buffer objects (BO) in the ivpu_gem_create_object() function. Specifically, when drm_gem_shmem_create() failed, the BO was not fully created, and the cleanup callback ivpu_gem_bo_free() was not invoked, leaving a deleted BO on the vdev->bo_list. This could lead to memory corruption and potentially compromise confidentiality, integrity, and availability.
AI Analysis
Technical Summary
The Linux kernel vulnerability CVE-2025-68730 affects the ivpu accelerator driver. The flaw occurs because the ivpu_gem_create_object() function adds a buffer object (BO) to the vdev->bo_list even when drm_gem_shmem_create() fails, resulting in an incomplete BO that is not properly freed. This leads to a page fault in ivpu_bo_unbind_all_bos_from_context() due to a stale BO reference. The issue was fixed by ensuring that BOs are not added to the list if creation fails, preventing use-after-free conditions and page faults.
Potential Impact
Successful exploitation can cause a page fault leading to kernel memory corruption. The CVSS vector indicates local attack vector with low complexity and low privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability. This means an attacker with local access could cause a denial of service or potentially escalate privileges by exploiting this flaw.
Mitigation Recommendations
A fix for this vulnerability has been implemented in the Linux kernel. Users and administrators should update to the fixed kernel version once available. Patch status is not yet confirmed in the provided data — check the official Linux kernel advisories or vendor updates for the exact fixed versions and apply them promptly.
