In the Linux kernel, the following vulnerability has been resolved:
ice: fix memory corruption bug with suspend and rebuild
The ice driver would previously panic after suspend. This is caused from the driver *only* calling the ice_vsi_free_q_vectors() function by itself, when it is suspending. Since commit b3e7b3a6ee92 ("ice: prevent NULL pointer deref during reload") the driver has zeroed out num_q_vectors, and only restored it in ice_vsi_cfg_def().
This further causes the ice_rebuild() function to allocate a zero length buffer, after which num_q_vectors is updated, and then the new value of num_q_vectors is used to index into the zero length buffer, which corrupts memory.
The fix entails making sure all the code referencing num_q_vectors only does so after it has been reset via ice_vsi_cfg_def().
I didn't perform a full bisect, but I was able to test against 6.1.77 kernel and that ice driver works fine for suspend/resume with no panic, so sometime since then, this problem was introduced.
Also clean up an un-needed init of a local variable in the function being modified.
PANIC from 6.8.0-rc1:
