Fix by storing allocated buffers into bp->queues[0] ASAP.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/23d42b9a3bcd55b17d3b371544fedc708c2397e9","tags":[]},{"url":"https://git.kernel.org/stable/c/259e6cbb6a097da8ced544ee92a6fbde35aa1338","tags":[]},{"url":"https://git.kernel.org/stable/c/bda487567d0b7b15dfa876511085c0666b9efad5","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
