A flaw was found in the Linux kernel's networking subsystem within the RPL protocol's handling. This issue results from the improper handling of user-supplied data, which can lead to an assertion failure. This flaw allows an unauthenticated, remote attacker to create a denial of service condition on the system. A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to achieve local privilege escalation.The out-of-bounds write is caused by missing skb- greater than cb initialization in the ipvlan network driver. The vulnerability is reachable if CONFIG_IPVLAN is enabled.We recommend upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e. 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
