Description A buffer overflow issue exists in the wilc1000 driver related to WID string configuration. The problem occurs during the parsing of response frames, specifically when copying data into the cfg->s[i]->str buffer. A size check has been added to prevent the overflow, based on the WID type received from the firmware and the size limits defined in the wilc cfg str vals structure. The vulnerable function is wilc wlan parse response frame().
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
