CVE-2022-3625

Se ha encontrado una vulnerabilidad en el Kernel de Linux. ha sido clasificada como crítica. Afecta a la función devlink_param_set/devlink_param_get del archivo net/core/devlink.c del componente IPsec. La manipulación conlleva a un uso de memoria previamente liberada. Es recomendado aplicar un parche para corregir este problema. Ha sido asignado el identificador VDB-211929 a esta vulnerabilidad

A flaw was found in the Netlink device interface implementation in the Linux kernel that improperly handled certain error conditions, leading to a use-after-free issue with some network device drivers. A local attacker with admin access to the network device could use this to cause a denial of service (system crash) or execute arbitrary code.

Jann Horn discovered that the Linux kernel did not properly track memory allocations for anonymous VMA mappings in some situations, leading to potential data structure reuse. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that a race condition existed in the memory address space accounting implementation in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.
