"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndevlink: Release nested relation on devlink free\n\ndevlink relation state is normally released from devl_unregister(), which\ncalls devlink_rel_put(). This misses devlink instances that get a nested\nrelation before registration and then fail probe before devl_register() is\nreached.\n\nThat flow can happen for SFs. The child devlink gets linked to its\nparent before registration, then a later probe error calls devlink_free()\ndirectly. Since the instance was never registered, devl_unregister() is not\ncalled and devlink->rel is leaked.\n\nRelease any pending relation from devlink_free() as well. The registered\npath is unchanged because devl_unregister() already clears devlink->rel\nbefore devlink_free() runs."
