KERNEL HOTFIXES LAND ACROSS MM, KEYS, AND EROFS AS ARCHINSTALL ADDS AARCH64 SUPPORT

Linus merged 13 memory management fixes cc:stable overnight, plus critical corrections to keyring array bounds and erofs page cache sharing that fix a NULL pointer dereference.

The biggest pull was a 13-hotfix batch from Andrew Morton covering memory management, keyring array trimming, and erofs regression fixes [1] [2] [3]. The keys fix addresses an unprivileged keyring vulnerability where description-chunk collisions drive assoc_array node splitting into out-of-bounds writes. Erofs also landed a critical fix: it was throwing NULL pointers during mincore() because page cache sharing lost a valid f_path reference. The pinctrl subsystem picked up an S4 sleep state fix for AMD machines and wakeup fixes for Qualcomm SC8280XP [4]. Over on Omarchy, DHH merged a package conflict recovery system that stops upgrades from aborting when pacman finds files it doesn't own, replacing the hand-maintained 25-entry allowlist that kept bitten users twice [5] [6]. Archinstall added AArch64 root partition type GUID support [7] and deduped systemd-resolved stub mode configuration [8], while Japanese translations hit 100% [9].

Action items

→ Pull kernel hotfixes if running memory-intensive or keyring-heavy workloads; erofs page cache NULL pointer fix affects mincore() callers torvalds/linux [immediate]
→ Review Omarchy package conflict recovery logic before next system upgrade basecamp/omarchy [plan]
→ Update Archinstall to latest if installing on AArch64 archlinux/archinstall [plan]
