| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.15.0-rc3-custom-45935-gce1adf704b14
Description
The Linux kernel has a vulnerability in the mlxsw thermal driver, which allows cooling states to be set above the maximum cooling state supported by the driver. This results in out-of-bounds memory accesses when thermal state transition statistics are enabled. The driver should reject such operations, and an error should be returned when the state to be set exceeds the maximum cooling state supported by the driver.
Recommendations
To resolve this issue, update the Linux kernel to a version that includes the fix for this vulnerability. Specifically, update to a version that is newer than 5.15.0-rc3-custom-45935-gce1adf704b14. Additionally, consider disabling the thermal state transition statistics feature until the update can be applied.
