Descriptions
An out-of-bounds (OOB) memory access flaw was found in x25_bind in net/x25/af_x25.c in the Linux kernel version v5.12-rc5. A bounds check failure allows a local attacker with a user account on the system to gain access to out-of-bounds memory, leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
Se encontró un fallo de acceso a la memoria fuera de los límites (OOB) en la función x25_bind en el archivo net/x25/af_x25.c en el kernel de Linux versión v5.12-rc5. Un fallo en la comprobación de límites permite a un atacante local con una cuenta de usuario en el sistema conseguir acceso a la memoria fuera de límites, conllevando a un bloqueo del sistema o una filtración de información interna del kernel. La mayor amenaza de esta vulnerabilidad es la confidencialidad, la integridad y la disponibilidad del sistema
