Linux Distros Unpatched Vulnerability : CVE-2025-40096

high Nessus Plugin ID 272063

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - drm/sched: Fix potential double free in drm_sched_job_add_resv_dependencies When adding dependencies with drm_sched_job_add_dependency(), that function consumes the fence reference both on success and failure, so in the latter case the dma_fence_put() on the error path (xarray failed to expand) is a double free.
 Interestingly this bug appears to have been present ever since commit ebd5f74255b9 (drm/sched: Add dependency tracking), since the code back then looked like this:
 drm_sched_job_add_implicit_dependencies(): ... for (i = 0; i < fence_count; i++) { ret = drm_sched_job_add_dependency(job, fences[i]); if (ret) break; } for (; i < fence_count; i++) dma_fence_put(fences[i]); Which means for the failing 'i' the dma_fence_put was already a double free.
 Possibly there were no users at that time, or the test cases were insufficient to hit it. The bug was then only noticed and fixed after commit 9c2ba265352a (drm/scheduler: use new iterator in drm_sched_job_add_implicit_dependencies v2) landed, with its fixup of commit 4eaf02d6076c (drm/scheduler: fix drm_sched_job_add_implicit_dependencies). At that point it was a slightly different flavour of a double free, which commit 963d0b356935 (drm/scheduler: fix drm_sched_job_add_implicit_dependencies harder) noticed and attempted to fix. But it only moved the double free from happening inside the drm_sched_job_add_dependency(), when releasing the reference not yet obtained, to the caller, when releasing the reference already released by the former in the failure case.
 As such it is not easy to identify the right target for the fixes tag so lets keep it simple and just continue the chain. While fixing we also improve the comment and explain the reason for taking the reference and not dropping it. (CVE-2025-40096)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
