Description

pds_core: make wait_context part of q_info

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

pds_core: make wait_context part of q_info

Make the wait_context a full part of the q_info struct rather

than a stack variable that goes away after pdsc_adminq_post()

is done so that the context is still available after the wait

loop has given up.

There was a case where a slow development firmware caused

the adminq request to time out, but then later the FW finally

finished the request and sent the interrupt. The handler tried

to complete_all() the completion context that had been created

on the stack in pdsc_adminq_post() but no longer existed.

This caused bad pointer usage, kernel crashes, and much wailing

and gnashing of teeth.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
