CVE-2022-27666

Se ha encontrado un fallo de desbordamiento del búfer de la pila en el código de transformación de IPsec ESP en net/ipv4/esp4.c y net/ipv6/esp6.c. Este fallo permite a un atacante local con un privilegio de usuario normal sobrescribir los objetos de la pila del núcleo y puede causar una amenaza de escalada de privilegios local

It was discovered that the network traffic control implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. 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 or possibly execute arbitrary code.
