Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data in net/netfilter/nf_tables_api.c.

Un error de confusión de tipos en la función nft_set_elem_init (conllevando a un desbordamiento del búfer) podría ser usado por un atacante local para escalar privilegios, una vulnerabilidad diferente a la de CVE-2022-32250. (El atacante puede obtener acceso de root, pero debe comenzar con un espacio de nombres de usuario no privilegiado para obtener acceso CAP_NET_ADMIN). Esto puede corregirse en la función nft_setelem_parse_data en el archivo net/netfilter/nf_tables_api.c",
