CVE-2022-47520: wifi: wilc1000: validate pairwise and authentication suite offsets · torvalds/linux@cd21d99
An issue was discovered in the Linux kernel before 6.0.11. Missing offset validation in drivers/net/wireless/microchip/wilc1000/hif.c in the WILC1000 wireless driver can trigger an out-of-bounds read when parsing a Robust Security Network (RSN) information element from a Netlink packet.
