Linux 6.18 Released
02 Dec 2025 tags: audit lsm selinuxLinux v6.18 was released on Sunday, November 30th. I already wrote up a post highlighting the LSM, SELinux, and audit changes that were submitted during the merge window. However, there were additional changes that went into Linux v6.18 that are described below.
SELinux
- Fix a problem where the per-task directory access cache introduced in Linux v6.16 was tied to a credential and not a task. An odd problem, largely caused by a changes over time and a failure to properly update the SELinux object security structure names due to those changes. The fix for this particular problem is to reintroduce a proper per-task security structure for SELinux and rename the existing per-credential security structure to better reflect it’s nature.
