An out-of-bounds buffer overflow has been found in the Linux kernel’s mac80211 subsystem when scanning for SSIDs. Address calculation using out-of-bounds array indexing could result in an attacker crafting an exploit, resulting in the complete compromise of a system.

Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: Avoid address calculations via out of bounds array indexing req->n_channels must be set before req->channels[] can be used. This patch fixes one of the issues encountered in [1].
