  • kernel: ipv6: validate extension header length before copying to cmsg (CVE-2026-63920)
  • kernel: drm/amd/display: set new_stream to NULL after release (CVE-2026-68236)
  • kernel: drm/dp/mst: fix buffer overflows in sideband chunk accumulation (CVE-2026-68278)
  • kernel: wifi: mac80211: defer link RX stats percpu free to RCU (CVE-2026-68409)
  • kernel: drm/amdgpu/vce: fix integer overflow in image size (CVE-2026-68108)
  • kernel: cifs: validate DFS referral string offsets (CVE-2026-72318)
  • kernel: drm/vmwgfx: use check_add_overflow for shader size+offset bound (CVE-2026-80887)
  • kernel: drm/amdkfd: Add TLB flush after MES queue eviction/suspension (CVE-2026-89811)
