Linux Kernel Daily: The Great Pre-Release Hardening Sweep
With 7.2 nearing release, this window is dominated by defensive fixes across input, USB, staging, and fbdev subsystems—bounds checks, validation, and use-after-free repairs—signaling a classic release-candidate cleanup pass rather than new feature work.

Good morning. It's August 9th, 2026, and this is Linux Kernel Daily.
Today's pattern is unmistakable: this is late-cycle hardening for the 7.2 release. Across sixteen merges, the dominant theme is input validation and bounds checking on data that comes from hardware or userspace.
Look at the Input subsystem pull, commit 7d8c681. Fixes for evdev information leaks, out-of-bounds access in focaltech and edt-ft5x06, and packet length validation in iforce. Dmitry Torokhov's summary calls out "information leaks and OOB accesses across several drivers" directly. The staging tree tells the same…
Second theme: cleanup of resource lifecycle bugs. The char-misc pull, commit 5668ba2, fixes memory and reference leaks in fastrpc across four separate patches, plus a lock-ordering fix in the mei driver. Powerpc's commit afe80ae fixes a memory leak in papr-phy-attest and a buffer underflow in lparcfg. These aren't…
Worth flagging separately: the futex fix in commit d4eee3b addresses a race in futex_pivot_pending during private hash resize that can leave tasks stuck. That's a correctness fix with real-world hang potential, not just a leak.
Also notable: the char-misc pull includes documentation…
