Linux Kernel: RC5 Fixes Sweep Across the Stack
This is a pure release-candidate stabilization cycle for kernel 7.2, with fixes converging on three recurring problems: use-after-free and reference-count races, error paths that leave state half-updated, and boundary or size-validation bugs in drivers and filesystems.

Good day. It's July 27th, 2026, and this is your Linux Kernel briefing.
Today's activity is entirely release-candidate cleanup heading into 7.2, pulled together from thirteen merge commits by Linus Torvalds. The dominant pattern: race conditions and lifetime bugs that only show up under real-world timing, now getting closed out before release.
Start with the VFS pull, tag vfs-7.2-rc5, the largest of the batch. Several fixes share a lifetime theme: eventpoll now pins files before checking reverse paths, because struct file became RCU-reclaimable and a concurrent close could let the check operate on a recycled file. Pid file descriptors got a matching fix,…
The tracing pull, tag trace-v7.2-rc4, follows the same script. A use-after-free in the event-enable trigger is fixed by deferring cleanup until after synchronization completes, rather than relying on timing that no longer holds now that workqueues are involved. A related fix moves a module reference count decrement…
Driver-level fixes reinforce a second theme: input validation. USB serial drivers reject oversized or malformed firmware headers in commits touching Io Edgeport, Io TI, and M X U port. The RTL8723BS staging driver fixes…
