hwmon

About this tag
The hwmon tag on WindowsForum.com covers the Linux kernel's hardware monitoring subsystem, which exposes sensors like temperatures, fan speeds, and PWM controls to user-space. Content includes discussions of driver-specific fixes, such as a TOCTOU race condition in the ftsteutates driver that could cause crashes or incorrect readings. While the tag is Linux-focused, it may be relevant to Windows users running Linux in virtual machines or dual-boot setups. Topics include kernel patches, driver stability, and sensor accuracy.

  1. Linux ftsteutates TOCTOU Fix: Read Once to Prevent Crashes

    The Linux kernel received a targeted fix addressing a subtle but real Time‑of‑Check to Time‑of‑Use (TOCTOU) race in the hwmon driver ftsteutates: the fts_read() path could read a shared fan source index twice without synchronization, opening a narrow window where a concurrent update changes the...
