If deletion fails, tca_action_gd() calls\ntcf_action_put_many() to release the remaining references, but its\ntcf_act_for_each_action() iterator stops at the first NULL slot.\n\nWhen a batch stops at an action bound to a filter, this leaks a\nreference on each subsequent action. A later delete of an unbound\naction can then return success without removing it from the IDR.\n\nWalk the full array in tcf_action_put_many() and skip NULL slots to\nrelease the references held on the unprocessed actions.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/1be63e4579af408d596f0f3165faf1a880631d3b","tags":[]},{"url":"https://git.kernel.org/stable/c/57b477e46ef2df3483f3488cc713c61c4b384aab","tags":[]},{"url":"https://git.kernel.org/stable/c/6e05e46fa821a5c1b281355f1f622ac76cb6080a","tags":[]},{"url":"https://git.kernel.org/stable/c/9eaba16f1b6ee19b249e6afd82c27f958d441458","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
