{"id":"AZL-102188","summary":"CVE-2026-93058 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/msm: Only fini scheduler after successful init\n\nmsm_ringbuffer_new() destroys a partially initialized ring through\nmsm_ringbuffer_destroy() when an allocation or scheduler setup step\nfails.\n\nIf drm_sched_init() fails before it finishes initializing the scheduler,\nthe failure path still calls drm_sched_fini(). That teardown path assumes\nthe scheduler work items, lists, and workqueue state were initialized.\n\nTrack successful scheduler initialization and call drm_sched_fini() only\nafter drm_sched_init() returned 0.\n\nThis issue was found by a static analysis checker and confirmed by\nmanual source review.\n\nPatchwork: https://patchwork.freedesktop.org/patch/738905/","modified":"2026-09-18T14:16:31.866197434Z","published":"2026-09-17T17:17:59Z","upstream":["CVE-2026-93058"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93058"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-102188.json"}}],"schema_version":"1.9.0"}
