Their different command sizes make native\ndispatch return -ENOIOCTLCMD.\n\nFor GET_FD, this overwrites receive_fd()'s return value after the\ndescriptor is installed, leaking one fd per call. Return handled compat\nresults directly and use native dispatch only for other commands.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/135ac58097fa5fc707bf392c5cececf59e4080c0","tags":[]},{"url":"https://git.kernel.org/stable/c/48a4ee65e677559776349128e6a81a6041986c99","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
