Linux Kernel 7.3.1 Release: KASLR Leak, Coredump Races, and io_uring Fixes

Linux kernel 7.3.1 shipped today, October 30, 2026, under Greg Kroah-Hartman as the first bugfix point of the 7.3 feature cycle, with 40 commits totaling 39 backported fixes. The headline work covers Christian Brauner's ten-patch series protecting coredump integrity during process teardown, plus a standout security fix that closes a KASLR pointer leak in the keyring subsystem. The release also rounds out io_uring, tracing, Bluetooth, and DAMON patches, and notably includes patches carrying "Assisted-by" credits for AI tools like Claude and DeepSeek. It's a recommended update for anyone on 7.3, though it carries no new features and should avoid the hardware surprises some AMD-GPU users saw with the parent release.
