Linux Kernel Daily: RC2 Targets Lifetime Bugs and Data Loss
Merges for Linux 7.4 release candidate 2 focus on use-after-free, locking, and memory corruption fixes across networking, memory management, and drivers. The dominant pattern is hardening object lifetimes and huge-page handling to prevent crashes, stalls, and silent data loss.

Hello, and welcome to Linux Kernel Daily for Friday, November 6th, 2026.
The signal this week is stabilization. Ahead of version 7.4 release candidate 2, maintainers are merging fixes almost entirely focused on lifetime bugs, bad locking, and silent data loss, not new features. If you reviewed networking or memory code recently, this directly affects you.
First, networking is chasing use-after-free and race conditions in connection setup. One fix, commit F-A-F-B-C-4-0, delays freeing IPv6 options on request sockets until after a read-copy-update grace period, because a migrated request clone can still be read while sending an acknowledgement. A related Multi-Path TCP…
Second, memory management is fixing corruption and loss, not performance. The core memory pull closes information leaks through pinned memory files and out-of-bounds writes during page pinning, plus data loss in shared memory, huge page collapse, and same-page merging. Other fixes address deadlocks between remapping…
Finally, a broad driver and filesystem sweep hardens the edges. Hardware monitoring sees dozens of sensor fixes for locking, false alarms, and bad readings. Virtio and virtual host fix queue setup and…
