kernel: sctp: validate cached peer INIT chunk length in COOKIE_ECHO processing

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A remote attacker could exploit this by sending a specially crafted COOKIEECHO chunk to a listening SCTP server. The server's failure to properly validate the length of a cached peer INIT chunk within...

kernel: Linux kernel: Wi-Fi subsystem out-of-bounds read via crafted frames

A flaw was found in the Linux kernel's Wi-Fi subsystem cfg80211. The cfg80211iselementinherited function does not properly validate the length of extension elements. A remote attacker, by sending a specially crafted Wi-Fi frame from an Access Point AP, could trigger a one-octet slab-out-of-bounds...
