Descriptions
A vulnerability was found in the Linux kernel's eBPF verifier when handling internal data structures. Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit mitigations in place for the kernel. This flaws affects kernel versions < v5.16-rc6
Se encontró una vulnerabilidad en el verificador eBPF del kernel de Linux cuando son manejados estructuras de datos internas. Las ubicaciones de memoria interna podían ser devueltas al espacio de usuario. Un atacante local con los permisos para insertar código eBPF en el kernel puede usar esto para filtrar detalles de memoria interna del kernel derrotando algunas de las mitigaciones de la explotación en el lugar para el kernel. Este fallo afecta a las versiones del kernel anteriores a v5.16-rc6
It was discovered that the BPF verifier in the Linux kernel did not properly restrict pointer types in certain situations. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Yiqi Sun and Kevin Wang discovered that the cgroups implementation in the Linux kernel did not properly restrict access to the cgroups v1 release_agent feature. A local attacker could use this to gain administrative privileges.
