Linux Kernel Daily: Late-Cycle Fixes Converge Before 7.2
Four merge commits landed ahead of the 7.2 release, all fix-only pulls covering memory management, erofs, pin control, and the keys subsystem, with a shared focus on correctness bugs found in edge cases like boundary checks, error paths, and non-present page table entries.

Good day. It's July 28th, 2026, and this is Linux Kernel Daily.
Today's story isn't one big feature, it's the opposite: a wave of stabilization fixes converging right before the 7.2 release, and the common thread is edge-case correctness.
Start with memory management. Andrew Morton's hotfix pull, merged by Linus in commit 62cc902, bundles thirteen fixes, eleven touching MM directly. Look at the pattern: list corruption in huge page file region allocation, bitmap overflow in per-CPU chunk creation, swap entry corruption when clearing write-protection…
Second theme: error-path hygiene. The pin control pull, commit e63c75f, fixes a double-free in device tree parsing when initialization fails, and the keys subsystem pull, commit aa6fc3d, fixes an out-of-bounds read and a slot write bug in the associative array structure used by keyrings. Different subsystems, same…
Third, smaller but concrete: the erofs pull, commit e895a6f, fixes a NULL pointer dereference in page cache sharing that was a recent regression, plus caps memory use for LZMA decompression on high core-count systems. And pin control also picked up a suspend fix for AMD systems around S4 sleep state handling, which…
What to…
