DEBIAN-CVE-2026-23323

In the Linux kernel, the following vulnerability has been resolved:  hwmon: (macsmc) Fix regressions in Apple Silicon SMC hwmon driver  The recently added macsmc-hwmon driver contained several critical bugs in its sensor population logic and float conversion routines.  Specifically: - The voltage sensor population loop used the wrong prefix ("volt-"   instead of "voltage-") and incorrectly assigned sensors to the   temperature sensor array (hwmon->temp.sensors) instead of the   voltage sensor array (hwmon->volt.sensors). This would lead to   out-of-bounds memory access or data corruption when both temperature   and voltage sensors were present. - The float conversion in macsmchwmonwritef32() had flawed exponent   logic for values >= 2^24 and lacked masking for the mantissa, which   could lead to incorrect values being written to the SMC.  Fix these issues to ensure correct sensor registration and reliable manual fan control.  Confirm that the reported overflow in FIELDPREP is fixed by declaring macsmchwmonwritef32() as alwaysinline for a compile test.
