CVE-2022-40279
An issue was discovered in Samsung TizenRT through 3.0_GBM (and 3.1_PRE). l2_packet_receive_timeout in wpa_supplicant/src/l2_packet/l2_packet_pcap.c has a missing check on the return value of pcap_dispatch, leading to a denial of service (malfunction).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.43%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
