Linux Kernel: Late-Cycle Fix Wave Across Subsystems

Four late-cycle pull requests landed fixes for ARC, SCSI, I2C, and s390, with several addressing use-after-free, memory leak, and security-adjacent bugs. The common thread is subsystem maintainers cleaning up resource handling and edge cases ahead of release.

Good day, and welcome to the briefing for July 19th, 2026.

Today's activity is four merge commits from Linus Torvalds, pulling fixes from ARC, SCSI, I2C, and s390 maintainers. No single change dominates, but a pattern runs through nearly all of them: resource lifecycle bugs — leaks, use-after-free, and stale state — getting cleaned up before release.

Start with SCSI, the largest of the four pulls, commit f2ec631. James Bottomley flagged a core fix to scsi_schedule_eh that closes a race causing error-handler hangs in libata and libsas — a reliability fix that matters for any system doing SCSI error recovery. Alongside it, driver-level leak fixes piled up: a DMA…

That same use-after-free pattern shows up again in I2C, commit ba6bd0d, where the mlxbf driver had a use-after-free in its resource init path. Two more i2c fixes, in the imx driver, address a locked bus condition during SMBus block reads under both interrupt and atomic contexts — the kind of bug that can wedge a bus…

s390, commit c6859ee, contributes two smaller but sharp fixes: a missing speculation barrier in the cpum_cf perf event code, guarding against a Spectre-style index attack from user-controlled event numbers, and a…
