Landlock only implements the \ncred_prepare hook, not cred_transfer, so KEYCTL_SESSION_TO_PARENT causes \nall information on Landlock restrictions to be lost. \n \nThis basically means that a process with the ability to use the fork() \nand keyctl() syscalls can get rid of all Landlock restrictions on \nitself. \n \nFix it by adding a cred_transfer hook that does the same thing as the \nexisting cred_prepare hook. (Implemented by having hook_cred_prepare() \ncall hook_cred_transfer() so that the two functions are less likely to \naccidentally diverge in the future.) \nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n \"Detection Date\": \"17 Aug 2024\",\n \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2024-08-17T12:18:01.000000Z"} 2024-08-17T12:18:01+00:00
