Descriptions
An out-of-bounds access vulnerability involving netfilter was reported and fixed as: f1082dd31fe4 (netfilter: nf_tables: Reject tables of unsupported family); While creating a new netfilter table, lack of a safeguard against invalid nf_tables family (pf) values within `nf_tables_newtable` function enables an attacker to achieve out-of-bounds access.
Se informó y solucionó una vulnerabilidad de acceso fuera de los límites que involucraba a netfilter como: f1082dd31fe4 (netfilter: nf_tables: Rechazar tablas de familia no admitida); Al crear una nueva tabla netfilter, la falta de protección contra valores no válidos de la familia nf_tables (pf) dentro de la función `nf_tables_newtable` permite a un atacante lograr un acceso fuera de los límites.
An out-of-bounds access vulnerability was found in the Linux Kernel. This issue occurs during the creation of a new netfilter table. The absence of safeguards in the nf_tables_newtable function against invalid nf_tables family (pf) values allows attackers to achieve unauthorized access. Exploitation occurs in two locations: the xt_find_target function in x_tables.c permits faking xt_af data, and the nf_logger_find_get function in nf_log.c can enable an attacker to use an invalid pf to dereference adjacent global data. By manipulating these values, an attacker could achieve unauthorized access beyond the intended boundaries.
