Description
A flaw was found in the Linux kernel's Landlock security module regarding the inheritance of LOG_SUBDOMAINS_OFF across process forks. When a process mutes subdomain logs using landlock_restrict_self() without creating a domain, this setting is not properly transferred to forked child processes. Consequently, these child processes may generate unexpected audit records, potentially leading to information disclosure.
