Readers call bcm_vk_drv_access_ok() before accessing the\nmessage queues and their cached queue information.\n\natomic_set()/atomic_read() do not order those accesses. A reader can see\nmsgq_inited set while still seeing stale queue information. Use release\nwhen publishing the initialized queues and acquire when checking the gate.\n\nKeep the clear in bcm_vk_blk_drv_access() as atomic_set(). It closes the\ngate and does not publish queue state to readers.","state":0,"publishedAt":"2026-09-17T16:10:41.716+00:00","modifiedAt":"2026-10-19T09:04:47.24+00:00","affected":[{"ecosystem":"Vendor
