Linux Kernel: Late-Cycle Fixes and a Wireless Regression Reversal
Torvalds pulled a heavy round of late-cycle fixes across networking, tracing, GPIO, and firewire subsystems, headlined by a reversion of a faulty mt76 WiFi fix that was hanging shutdown and module unload on affected hardware.

It's August 14, 2026, and this is your Linux Kernel briefing.
The dominant theme today is release stabilization. This is late-cycle cleanup, with maintainers pulling in fixes rather than features, and one of those fixes had to undo a previous fix that made things worse.
Start with wireless. Commit 3aa1dca reverts a change to the mt76 driver that disabled NAPI when removing a device. That original fix was meant to silence warnings on one chipset, but on mt7921 and mt7925 hardware it caused a double-disable that isn't idempotent — the kernel would spin forever waiting for state that…
That same networking pull is otherwise a grab bag of real-world reliability fixes: a refcount leak in ipset, a use-after-free in IPv4 route MTU updates, a socket buffer leak in traffic control, and fixes across veth, ngbe, and gve drivers. The common thread is defensive hardening — closing races and null pointer…
Tracing gets similar treatment. Two commits, c3730b8 and b698592, fix race conditions and a null pointer crash when loading kernel modules that register trace events concurrently. Both are locking bugs — missing mutex protection around shared event field lists, and a missing null check on cached…
