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...

CVE-2026-93784 wifi: cfg80211: validate IEs in cfg80211_wext_siwgenie()

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: validate IEs in cfg80211wextsiwgenie The KASAN allocation trace shows that a malformed IE buffer is stored via SIOCSIWGENIE cfg80211wextsiwgenie without any validation. The crash trace shows that a subsequent...

kernel: net: tun: bound receive headroom

A flaw was found in the Linux kernel's TUN/TAP driver. An integer underflow vulnerability exists in the tungetuser function when processing oversized headroom requests. This can occur if Open vSwitch OVS propagates an excessively large headroom request to the TUN or TAP device. Successful...
