Descriptions

arch/i386/kernel/sysenter.c in the Virtual Dynamic Shared Objects (vDSO) implementation in the Linux kernel before 2.6.21 does not properly check boundaries, which allows local users to gain privileges or cause a denial of service via unspecified vectors, related to the install_special_mapping, syscall, and syscall32_nopage functions.

arch/i386/kernel/sysenter.c en la implementación Virtual Dynamic Shared Objects (vDSO) para el kernel de Linux anterior a v2.6.21, no comprueba de forma adecuada los límites; esto permite a usuarios locales ganar privilegios o provocar una denegación de servicio a través de vectores no especificados. Está relacionado con las funciones install_special_mapping, syscall y syscall32_nopage.
