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.
