Good morning, this is Linux Kernel Daily for June 11th, 2026.

Today's activity centers on release candidate stabilization, with three focused fixes addressing security, performance, and hardware-specific issues as the 7.1 kernel approaches final release.

The most significant change comes from a namespace security fix in commit 805d5a2. The patch restricts the open tree namespace and filesystem mount namespace operations to directories only, preventing a vulnerability where regular files could be mounted over directory namespace roots. This matters because it was…

RISC-V architecture received important control flow integrity updates through commit 7676223. The changes improve the CFI branch landing pad control implementation to properly reject unknown control bits with negative EINVAL responses, rather than silently ignoring invalid requests. The merge also addresses a…

AMD processor users will see power management improvements from commit 9716c08, which fixes the AMD P-state driver's handling of energy performance preference values. The driver was incorrectly blocking zero EPP values in performance mode, and the fix removes this unnecessary restriction while cleaning up outdated…
