Use it here too.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/50e8d70ba0743f88afd7e49f9cebd1841ee677f5","tags":[]},{"url":"https://git.kernel.org/stable/c/d94787287a113a1326211647d5e0deed1e9de105","tags":[]},{"url":"https://git.kernel.org/stable/c/e9b4c00f775a915b759b08bfe2c5e806a8301a59","tags":[]},{"url":"https://git.kernel.org/stable/c/f501302ebb9e1504162351b951fe3ae331c852ab","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
