USN-5357-1: Linux kernel vulnerability

First published: Thu Mar 31 2022(Updated: )

It was discovered that the IPsec implementation in the Linux kernel did not properly allocate enough memory when performing ESP transformations, leading to a heap-based buffer overflow. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
