Linux Kernel: Session Security and Network Hardening
Two late-cycle merges landed today, one tightening SMB server session and authentication handling from Steve French's ksmbd tree, and another pulling nearly a hundred networking fixes touching Bluetooth, netfilter, and several NIC drivers.

It's July 10th, 2026, and this is your Linux Kernel briefing.
Today's activity centers on one clear theme: authentication and session integrity got a hard look across two different subsystems.
First, the SMB server. Commit a635d67 merges a batch of ksmbd fixes from Steve French, and nearly all of them touch session setup and multichannel binding. The kernel now enforces the 32-channel session limit, keeps derived channel keys separate from the main session key, and rejects channel binding attempts from a…
Second, the networking pull in commit 2c7c88a, curated by Paolo Abeni, reads like a security and stability sweep. Bluetooth gets three fixes for use-after-free and null-pointer conditions in connection handling. Netfilter closes a use-after-free and memory leak in IGMP and MLD, caps expectations per master to…
The throughline: both merges are dominated by session, authentication, and memory-safety corrections rather than new features. That's typical for a late release candidate, and it's a signal these are stabilization patches, not exploratory work.
What to remember: if you're running SMB multichannel setups or touching ksmbd session code, review the reauthentication and binding…
