Linux Kernel: Two Architecture Fix Pulls Land
Linus Torvalds merged fix batches for MIPS and s390, both focused on correctness and safety rather than new features. The s390 changes close a kernel buffer overflow risk and a key-verification bug, while the MIPS batch covers memory, IRQ, and platform device cleanup.

Good day, and welcome to Linux Kernel briefing for July fifth, twenty twenty-six.
Today's activity is small but pointed: two architecture-level fix pulls, both landing late-cycle corrections rather than new capability.
The s390 pull, commit seven-four-oh-four-c-e-five, is the one worth remembering. Vasily Gorbik's fixes address two distinct security-relevant bugs. First, the monwriter driver was allowing buffer reuse with a different data length than originally allocated, which opened the door to an out-of-bounds copy from user…
The MIPS pull, commit four-one-oh-four-three-oh-b from Thomas Bogendoerfer, is more of a routine cleanup batch: a highmem check before removing a memory block, an IRQ work mechanism for Loongson64 based on self-IPI, vDSO build salt, and RTC device deregistration cleanup on the DEC platform for cases where setup…
The common thread across both pulls: these are defensive fixes, not features. Buffer length validation, bounds checking before memory operations, and proper cleanup on failure paths. That's a healthy sign for a stabilization window.
What's next: if you maintain code touching pkey verification or monwriter on s390, confirm you're picking up this fix…
