CVE-2026-93784

A vulnerability exists in the Linux kernel 's cfg80211 component. The function cfg80211_wext_siwgenie() fails to validate the IE buffer stored via SIOCSIWGENIE , leading to an out-of-bounds read in skip_ie() and an integer underflow in memcpy during a subsequent SIOCSIWESSID connection attempt. T...
