UBUNTU-CVE-2025-40096

In the Linux kernel, the following vulnerability has been resolved: drm/sched: Fix potential double free in drmschedjobaddresvdependencies When adding dependencies with drmschedjobadddependency, that function consumes the fence reference both on success and failure, so in the latter case the...

CVE-2025-40096

CVE-2025-40096 is a Linux kernel issue in the drm/sched subsystem. The vulnerability is a potential double free in the path that adds dependencies via drm_sched_job_add_dependency() and drm_sched_job_add_resv_dependencies() , where a fence reference may be released twice on failure. The defect ap...
