摘要:

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

media: intel/ipu6: remove cpu latency qos request on error

Fix cpu latency qos list corruption like below. It happens when
we do not remove cpu latency request on error path and free
corresponding memory.

[ 30.634378] l7 kernel: list_add corruption. prev->next should be next (ffffffff9645e960), but was 0000000100100001. (prev=ffff8e9e877e20a8).
