kernel: buffer overflow in IPsec ESP transformation code

A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat...

The vulnerabilities of the esp4 and esp6 modules in the Linux kernel allow attackers to enhance their privileges.

The vulnerability of the esp4 and esp6 modules in the Linux kernel relates to the execution of operations outside the buffer boundaries in memory. Exploiting this vulnerability can allow an attacker to increase their privileges...
