Background
The bonding package is a part of the Linux Kernel ecosystem and is responsible for creating a network interface bond. This bond combines multiple network interfaces into a single logical interface, providing fault tolerance and load balancing. The bonding package is widely used in Linux systems to enhance network connectivity and reliability.
Vulnerability Detail
The null dereference vulnerability in the bonding package, specifically in the bond_ipsec_add_sa() function, allows an attacker to trigger a null pointer dereference. This vulnerability was introduced in version v5.9 of the Linux Kernel and was fixed in version v5.10.54. An attacker could exploit this vulnerability to cause a denial-of-service (DoS) condition by sending specially crafted network packets. The impact and attack plausibility of this vulnerability have not been proven yet.
