Welcome to Linux Kernel Daily for the week of September 14 through September 21, 2026.
Quick stats: 0 pull request activity items, 30 additional commits this week.
Our lead insight is stabilization over features, with the project focused on object lifetimes, memory safety, and correct hardware handling ahead of the 7.3 series.
First, lifetime and concurrency fixes. A timer update anchored in commit 0a15ba6 addresses races between timer signals and process execution that could lead to use after free, cleaning up POSIX CPU timers after thread teardown and between expiry and reset. A related DMA engine merge, commit a10a019, corrects channel…
Second, processor and resume reliability. An x86 urgent merge, commit 156fa74, rejects a problematic microcode version on Intel Granite Rapids systems, restores signal context for rejected interrupt instructions under FRED, and prevents native builds from using unsupported extended registers. Separately, commit…
Third, input and access control hardening. Commit b12dd0f zeroes stack structures before copying force feedback and joystick calibration data to user space, preventing kernel stack disclosure, and clamps device supplied report sizes and…
