Linux Kernel: Late-Cycle Fixes Converge on Race Conditions and Resource Leaks
This wave of merges into the main tree is dominated by hardening fixes—races, use-after-free bugs, and resource leaks—pulled in from RDMA, memory management, memblock, NFS server, and 9p filesystem subsystems ahead of release.

Good day, it's September 15th, 2026, and this is your Linux Kernel briefing.
The signal across today's merges is consistency: this is release-stabilization work, heavy on race conditions, memory safety, and resource cleanup, not new features.
Start with the RDMA pull, commit 01414b7, twenty-eight fixes deep. Jason Gunthorpe's summary reads like a security checklist: remote-triggerable races in siw and rxe, a lockdep loop in disassociation handling, a race in ucma multicast joins, and bnxt underscore re leaking physical addresses to userspace. The…
Memory management shows the same pattern at smaller scale. The mm hotfixes pull, commit 164f652, fixes a shrinker bug that misbehaves under cgroup memory constraints, corrects locked-memory accounting during a specific remap flag, and closes a swap usage counter collision that could corrupt accounting. Ten of the…
Memblock's fix, in commit ebb58ec, is narrower but worth noting: debugfs wasn't displaying all flags on a memory region, which matters for anyone debugging boot-time memory layout issues.
Two filesystem fixes round things out. The NFS server fix in commit 5878583 corrects how the netlink export path handles the parallel NFS flag —…
