In the Linux kernel, the following vulnerability has been resolved:
pds_core: fix auxiliary device add/del races
Two paths add or delete the same slot (pf->vfs[vfid].padev): a VF's pdscresetdone() and the PF's devlink enablevnet/disablevnet handler. They serialize on configlock, but neither guards the slot under it correctly.
add() registers and stores a new auxiliary device without first checking the slot, so a second add of an already-populated slot leaks the first device. del() makes that check outside config_lock, so two concurrent dels can both pass it; the first clears the slot, and the second dereferences a NULL pointer.
Check and update the slot under config_lock in both paths.
