Linux Kernel Daily: The Merge Window Closes Out
Linus pulled nine major subsystem trees today, and the dominant thread is use-after-free and lifetime bug fixes landing across completely unrelated corners of the kernel, from RDMA to power supply drivers to SCSI. A smaller but notable thread: two subsystems, Landlock and modules, both got deep internal refactors aimed at better observability and debugging.

It's August 22nd, 2026, and this is Linux Kernel Daily.
The big story today isn't any single feature, it's how many pulls this cycle were dominated by use-after-free and object-lifetime fixes, showing up independently across drivers, RDMA, and filesystems.
Start with power supply, commit 2be02a7: multiple drivers, including U C S 1002, L P 8788 charger, and A B 8500 fuel gauge, all got use-after-free fixes on device removal. That's the same bug class, repeated across at least five separate charger and battery drivers, suggesting a common pattern of drivers not…
The second theme is observability and hardening in security-adjacent code. Landlock, commit 7199989, added a full set of tracepoints for domain enforcement, rule checking, and ptrace or network denials, plus a new flag, Landlock restrict self no new privs, for more consistent process-wide enforcement. That required…
eCryptfs, commit af33c5a, fits this pattern too — bounds checking on malicious lower-file metadata and hardened miscdev message handling, plus a couple of locking fixes on the daemon message queue.
Elsewhere, DRM's pull, commit 4e69c18, was the largest by far, with AMD GFX 6 through 8 modifier support and dmemcg…
