Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel’s mac80211 component related to insufficient buffer length validation during hardware scanning. Specifically, the S1G capability element was not accounted for in the
scan ies len, leading to a buffer overflow in the ieee80211 prep hw scan() function and a warning in ieee80211 start scan(). This prevents hardware scanning from functioning correctly.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
