UBUNTU-CVE-2026-93058: Low severity ubuntu/linux-hwe-edge vulnerability
In the Linux kernel, the following vulnerability has been resolved: drm/msm: Only fini scheduler after successful init msmringbuffernew() destroys a partially initialized ring through msmringbufferdestroy() when an allocation or scheduler setup step fails. If drmschedinit() fails before it finishes initializing the scheduler, the failure path still calls drmschedfini(). That teardown path assumes the scheduler work items, lists, and workqueue state were initialized. Track successful scheduler initialization and call drmschedfini() only after drmschedinit() returned 0. This issue was found by a static analysis checker and confirmed by manual source review.
