Description
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.
Affected configurations
• linux linux kernel (>= 6.4 < 6.6.89)
• linux linux kernel (>= 6.7 < 6.12.26)
• linux linux kernel (>= 6.13 < 6.14.5)
• linux linux kernel 6.15
