Summary
linux-aws-hwe, linux-azure, linux-gcp, linux-gcp-4.15, linux-oracle, linux-raspi2 vulnerability
Details

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.
