Summary

linux-oem-5.14 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.
