Linux Kernel: Late-Cycle Hotfix Sweep
Four merge commits landed late-cycle fixes across memory management, file systems, pin control, and the keyring subsystem, with two of them addressing out-of-bounds memory bugs. The common thread is stabilization work ahead of release, not new features.

This is Linux Kernel for July 28th, 2026.
Today's activity is entirely stabilization work — four merge commits, all pulling in fixes rather than features, and the pattern that stands out is memory safety.
Start with the keys subsystem. Jarkko Sakkinen's pull, commit aa6fc3d, fixes an out-of-bounds slot write in the associative array code — triggered when colliding key descriptions push keyring node-splitting into bad memory. That's paired with a related out-of-bounds read fix in keyring chunk handling. Two separate…
Memory management gets the same treatment at larger scale. Andrew Morton's mm hotfixes pull, commit 62cc902, bundles thirteen fixes, all marked for stable backport. Highlights include a list corruption bug in huge page file region allocation, a swap entry corruption issue when clearing userfault write-protection at…
The Erofs pull, commit e895a6f, fixes a regression causing a null pointer dereference in page cache sharing during mincore calls, plus a cap on LZMA stream memory usage for high-core-count systems — a resource exhaustion fix as much as a correctness one.
Pin control, commit e63c75f, is smaller in scope but includes one fix worth remembering: an AMD driver was…
