Descriptions
An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7. It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets. This may result in denial of service or privilege escalation.
Se descubrió un problema en fl_set_geneve_opt en net/sched/cls_flower.c en el kernel de Linux antes de 6.3.7. Permite una escritura fuera de los límites en el código flower classifier a través de paquetes TCA_FLOWER_KEY_ENC_OPTS_GENEVE. Esto puede resultar en denegación de servicio o escalada de privilegios.
A flaw was found in the TC flower classifier (cls_flower) in the Networking subsystem of the Linux kernel. This issue occurs when sending two TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets with a total size of 252 bytes, which results in an out-of-bounds write when the third packet enters fl_set_geneve_opt, potentially leading to a denial of service or privilege escalation.
