Description
Description
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.
