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 intr...
