"value": "In the Linux kernel, the following vulnerability has been resolved:\n\npds_core: fix auxiliary device add/del races\n\nTwo paths add or delete the same slot (pf->vfs[vf_id].padev): a VF's\npdsc_reset_done() and the PF's devlink enable_vnet/disable_vnet handler.\nThey serialize on config_lock, but neither guards the slot under it\ncorrectly.\n\nadd() registers and stores a new auxiliary device without first checking\nthe slot, so a second add of an already-populated slot leaks the first\ndevice. del() makes that check outside config_lock, so two concurrent\ndels can both pass it; the first clears the slot, and the second\ndereferences a NULL pointer.\n\nCheck and update the slot under config_lock in both paths."
