- Summary
- CVE-2026-72397 affecting package kernel 6.6.150.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
hwmon: (pmbus/core) honor vrmversion in pmbusdata2reg_vid()
pmbusdata2regvid() hardcoded the VR11 encoding regardless of the vrmversion configured by the driver, while pmbusreg2datavid() already switched on it. Any driver that selects a non-VR11 VID mode and exposes a regulator (or hwmon vout setter) sent dangerously wrong codes to PMBUSVOUT_COMMAND -- e.g. an nvidia195mv part asked for 200 mV got the VR11 clamp to 500 mV encoded as 0xB2, which the chip interprets as 1080 mV.
Mirror pmbusreg2datavid() so writes round-trip with reads.
