| Doc Text: |
A flaw was found in the Linux kernel's Wi-Fi subsystem, specifically within the `cfg80211` component. This vulnerability, located in the `cfg80211_wext_siwscan()` function, can lead to a memory leak. A local attacker could exploit this by sending a crafted Wi-Fi scan request with an Extended Service Set Identifier (ESSID) exceeding the maximum allowed length. This improper handling of the oversized ESSID causes a `creq` object to not be properly freed, potentially leading to a denial of service.
