Descriptions

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.

Se descubrió un problema en el kernel de Linux anterior a 6.0.11. La falta de validación de compensación en drivers/net/wireless/microchip/wilc1000/hif.c en el controlador inalámbrico WILC1000 puede desencadenar una lectura fuera de los límites al analizar un elemento de información Robust Security Network (RSN) de un paquete Netlink.
