CVE-2026-23323

Description

A flaw was found in the Linux kernel's macsmc-hwmon driver, which is responsible for managing hardware monitoring on Apple Silicon systems. Incorrect sensor population logic could lead to out-of-bounds memory access or data corruption. Additionally, a flaw in the float conversion routines could result in incorrect values being written to the System Management Controller (SMC), a subsystem that controls hardware functions. These issues could lead to system instability or unreliable manual fan control.
