LINUS PULLS INTEGRITY FIX FOR TPM-BYPASS
By RepoJournal · Filed · About Arch Linux
Linus merged the integrity-v7.3 tag, addressing a TPM initialization race that could silently bypass IMA.
The kernel's integrity subsystem now lets builders defer IMA initialization with CONFIG_IMA_INIT_LATE_SYNC, fixing a race where IMA could fall back to TPM-bypass mode [1]. Smack lands a critical UAF fix in smack_file_send_sigiotask() plus tightened 0-255 limits on smackfs interfaces [2]. Chrome platform gets a memory overread fix in cros_ec_sensorhub and a resource leak fix in cros_ec_debugfs, alongside a new post_power_on_delay_ms for Hana [3]. Input adds the Imagis ISA1200 haptic driver and hardens core open/close/inhibit paths [4]. PWM sees cleanups in C and Rust with a new SoC variant supported [5]. On the package side, ostree 2026.4-1 hits extra-x86_64 [6], while fvm 4.1.4-1 enters extra-testing [7] and the LTS driver trio of tp_smapi-lts, r8168-lts, and nvidia-open-lts all moved to stable [8][9][10].

Action items
- → Rebuild kernels with CONFIG_IMA_INIT_LATE_SYNC if TPM is used and IMA bypass is a concern archlinux/linux [plan]
- → Upgrade to ostree 2026.4-1 on extra-x86_64 archlinux/state [monitor]
- → Test fvm 4.1.4-1 in extra-testing to catch regressions before stable archlinux/state [plan]
- → Install the promoted LTS drivers (tp_smapi-lts, r8168-lts, nvidia-open-lts) from extra archlinux/state [monitor]
