KERNEL 7.2-RC1 CLOSES OUT HARDWARE DRIVERS WITH CRITICAL FIXES ACROSS FBDEV, RTC, PWM, SOUND, AND I2C

By RepoJournal · Filed 06:01 UTC on June 28, 2026 · About Linux

Four subsystem pull requests landed overnight addressing hardware state machine corruption, heap leaks in audio sequencer core, and variable overflow bugs that could cause device misconfiguration.

The fbdev merge [1] fixes NULL pointer dereference risks in console code and cleans up error paths across multiple framebuffer drivers, a seemingly routine housekeeping change that actually prevents crashes on certain display configurations. More consequentially, the pwm fixes [2] address a variable overflow bug causing misconfigurations in pulse-width modulation hardware, the kind of silent failure that ships broken to production if you're not looking. The sound merge [3] patches an uninitialised heap leak in the ALSA sequencer core and a resource leak in compress-offload, both potentially exploitable in certain workloads. RTC subsystem [4] removes the now-orphaned pcap driver after Motorola EZX support was dropped, adds oscillator stop flag handling to ds1307 variants, and introduces rtc_read_next_alarm() for timer-aware applications. I2C closes the window [5] with fixes to the i801 hardware state machine corruption path and timeout calculation errors in mpc that could hang bus transfers.

Action items

→ Test pwm hardware configurations after upgrade - variable overflow fix affects active deployments torvalds/linux [plan]
→ Review audio pipeline error handling if you use compress-offload - resource leak now patched torvalds/linux [monitor]
→ Remove pcap RTC driver references from device tree configs before 7.2 final torvalds/linux [plan]
