Linux Kernel: SMB Hardening and Perf Parity
SMB client and server merges validate response lengths and fix use-after-free and overflow flaws, while AppArmor and fsverity close mediation and integrity bypasses. Perf tools add ARM64 data-type profiling and Python modernization amid late-window DRM, KVM, and power fixes.

Good morning, it's Saturday, October thirty-first, twenty twenty-six, and this is your Linux Kernel briefing.
The through-line today is trust-no-input: both ends of Windows file sharing learned to distrust length and offset fields, while AppArmor and file verity closed similar bypasses.
First, file sharing hardening. The server-side merge and the client-side fixes tackle the same failure mode from opposite directions. The server now sizes compound create responses and directory name conversions correctly, fixes a remote direct memory access length underflow, and closes use-after-free paths on…
Second, confinement and integrity. AppArmor fixes leaks on failed policy loads, a use-after-free in namespace lookup, an integer overflow in table sizing, and gaps in socket mediation for unspecified addresses and S C T P connects and binds. File verity now sets its verified flag only after rollback is impossible…
Finally, observability and hardware churn. Perf tools gain instruction tracking on ARM sixty-four for data type profiling, modernized Python exporters, hardened just-in-time dump parsing, and safer config handling. Display and virtualization pick up late merge-window stability:…
