Good day, and welcome to Linux Kernel Daily for August 3rd, 2026.
Today's headline is release mechanics: Linus Torvalds tagged 7.2-rc6, and the merges feeding into it lean heavily toward security and memory-safety corrections rather than new features. That's the pattern worth remembering as this cycle closes out.
Start with s390. Vasily Gorbik's pull, commit 0e67278, fixes a cluster of zcrypt problems: CPRB buffer overflows in CCA AES and ECC key handling, out-of-bounds permission bitmap access in EP11 filtering, and speculative reads from user-controlled domain indexes. There's also a fix to scrub sensitive key material…
The VFS pull, commit bd1dde8, tells a similar story in a different subsystem. Binfmt_misc gets five separate fixes, including a mount pinning itself indefinitely through its own interpreter, a write-access leak that permanently broke reopening a file, and an out-of-bounds read triggered by a malformed delimiter.…
Outside those two, the SCSI pull, commit a84c804, is notable mainly for reverting the threaded interrupt handler in UFS core - a rollback rather than a forward fix, signaling that change wasn't ready. RISC-V, dmaengine, and PHY pulls round out the usual…
