Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A flaw exists in the Linux kernel related to the handling of ACPI DSD methods within the QuickI2C driver. Specifically, the ICRS and ISUB data returned by these methods include a trailing byte, resulting in an incorrect length calculation. This discrepancy can lead to a stack-out-of-bounds write and ultimately a kernel crash. The issue occurs during the processing of ACPI resources, potentially impacting system stability.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
