CVSS: 6.7EPSS: 0%CPEs: 1EXPL: 0CVE-2022-2785 – Arbitrary Memory read in BPF Linux Kernel
https://notcve.org/view.php?id=CVE-2022-2785
There exists an arbitrary memory read within the Linux Kernel BPF - Constants provided to fill pointers in structs passed in to bpf_sys_bpf are not verified and can point anywhere, including memory not owned by BPF. An attacker with CAP_BPF can arbitrarily read memory from anywhere on the system. We recommend upgrading past commit 86f44fcec22c Se presenta una lectura de memoria arbitraria dentro del BPF del Kernel de Linux - Las constantes proporcionadas para rellenar los punteros en los structs pasados a bpf_sys_bpf no son verificados y pueden apuntar a cualquier lugar, incluyendo la memoria que no es propiedad de BPF. Un atacante con CAP_BPF puede leer arbitrariamente la memoria de cualquier parte del sistema. Recomendamos actualizar el commit pasado 86f44fcec22c • https://git.kernel.org/bpf/bpf/c/86f44fcec22c https://lore.kernel.org/bpf/20220816205517.682470-1-zhuyifei%40google.com/T/#t • CWE-125: Out-of-bounds Read •
