Linux kernel is the kernel used by the Linux Foundation’s open source operating system, Linux. Linux kernel is vulnerable to a buffer overflow vulnerability that results from not properly validating data boundaries when executing operations on net/ipv4/esp4.c and net/ipv6/esp6.c in memory. A local attacker could exploit this vulnerability to overflow the buffer and execute arbitrary code on the system or gain elevated privileges in certain configurations.
