Linux Kernel Daily: The Merge Window Closes on Race Conditions and Resource Leaks
This merge window's pulls, spanning remoteproc, rpmsg, USB, TTY, and KVM, are dominated by fixes for lifecycle races, use-after-free bugs, and reference leaks rather than new features. The clear signal is a kernel-wide push to harden teardown and error paths across subsystems.

Good day. It's August 26th, 2026, and this is Linux Kernel Daily.
Today's pull requests tell one consistent story: teardown and cleanup paths are getting hardened across the tree. When drivers shut down, detach, or hit errors, that's where the bugs live, and that's where today's fixes concentrate.
Start with remoteproc and rpmsg, both from Bjorn Andersson. The rpmsg pull fixes a deadlock in GLINK endpoint destruction during driver detach, and closes a race where remoteproc shutdown and a userspace destroy-endpoint ioctl could both try to tear down the same character device. The much larger remoteproc pull,…
That same pattern shows up in USB. The pull in f4d5081 reads like a use-after-free tour: UVC gadget function bind and unbind, USB file system device release, audio gadget sound card disconnect, and a DWC3 gadget endpoint race. Each is a different driver, same root cause—objects getting freed while something else…
TTY and serial, in 70f5376, fix the same class of problem: clearing character device pointers after failed registration, and skipping cleanup calls when there's nothing to clean up. Char and misc drivers, in 93e4b30, add power-management reference leak fixes across a…
KVM's…
