Work that runs after\nucsi_unregister() has been called touches freed state: it dereferences\nthe connector array that ucsi_unregister() freed, or registers and\nunregisters the instance a second time.\n\nDisable both work items with disable_work_sync() before unregistering,\nand unregister only if the instance is still registered.\n\nThis issue was found by an in-house static analysis tool.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/41934f92e7a54d4080ac0b17aacc83224946785c","tags":[]},{"url":"https://git.kernel.org/stable/c/432b58cd959e594909a581b4974396cdbc9d4ca1","tags":[]},{"url":"https://git.kernel.org/stable/c/63b269ec537dc0fd26d0bd64872c26860d108c9d","tags":[]},{"url":"https://git.kernel.org/stable/c/ee8577de01c6b6c7dd1d76b52242c54d37a989f4","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
