Overview

What is CVE-2026-93052?

In the Linux kernel, the following vulnerability has been resolved:

misc: bcm-vk: Use acquire/release for msgq_inited

bcm_vk_sync_msgq() fills the message queue information and then sets msgq_inited. Readers call bcm_vk_drv_access_ok() before accessing the message queues and their cached queue information.

atomic_set()/atomic_read() do not order those accesses. A reader can see msgq_inited set while still seeing stale queue information.

Use release when publishing the initialized queues and acquire when checking the gate.

Keep the clear in bcm_vk_blk_drv_access() as atomic_set(). It closes the gate and does not publish queue state to readers.
