Good morning. It's August 27th, and this is Linux Kernel Daily.
The signal today is late-cycle cleanup: multiple subsystems pulling in fixes for use-after-free bugs, race conditions, and error-path mistakes rather than new features. That's a strong sign the seven-point-three window is closing and maintainers are tightening loose ends.
Start with NFS, in commit 73e3f07. Trond Myklebust's pull covers a use-after-free in the sunrpc client, a delegation hash table leak, and a NULL dereference on lockowner allocation failure. These are the kinds of bugs that show up under real-world load and memory pressure, so this is a reliability-focused pull…
That same pattern repeats in AppArmor, commit 8fefe68. The headline fix, from Jann Horn, addresses a credential use-after-free caused by how AppArmor updates stale credentials after a policy replacement — now deferred to task work at the end of the syscall. Alongside it: a race condition in label replacement, a…
ACPI, commit 3382bfb, follows suit — fixing a stack buffer overflow in the platform firmware runtime update driver, a bus ID cleanup bug on device-add failure, and adding mutex protection to the battery driver to stop race conditions…
