IOMMU AND SMB3 SECURITY FIXES LAND IN RC2 AS DRM RACE CONDITION PATCHED

Critical security fixes for AMD-Vi and SMB3 hit the kernel overnight while DRM's handle-change ioctl finally gets its use-after-free sealed.

The IOMMU subsystem [1] pulled in a high-priority security fix for AMD's SEV-SNP enabled systems alongside a cache-flushing bug that was breaking non-x86 platforms — both land in RC2 and both need to ship before 7.1 final. The SMB client stack [2] got hammered with fixes: two ACL validation holes, out-of-bounds reads in symlink handling, and a critical Kerberos-AES-256 path that was failing silently in production environments. On the graphics side, Dave Airlie's DRM pull [4] is dominated by a nasty race condition in the handle-change ioctl [3] where concurrent gem_close operations could trigger use-after-free — the fix mirrors gem_close's own safety dance. SPI drivers also took their lumps: Microchip QSPI and Freescale i.MX had production-grade issues that are now closed [5]. Over in the omarchy desktop layer, packaged Dell XPS haptic support [6] went out of tree, reminders got a speed boost [7], and VAAPI GL crashes on some Chromium builds are finally gone [8].

Action items

→ Test AMD-Vi and SMB3 fixes immediately if running SEV-SNP or Kerberos-AES-256 [ref:1][ref:2] torvalds/linux [immediate]
→ Backport DRM handle-change race fix to 7.0 LTS before next point release [ref:3] torvalds/linux [immediate]
→ Verify SPI device stability on Microchip QSPI and i.MX systems [ref:5] torvalds/linux [plan]
→ Update Dell XPS systems to new packaged haptics and remove legacy in-repo service [ref:6] basecamp/omarchy [plan]
