CVE-2011-1577

Desbordamiento de búfer basado en memoria dinámica en la función is_gpt_valid en fs/partitions/efi.c en el kernel de Linux v2.6.38 y anteriores, permite a atacantes físicamente próximos causar una denegación de servicio (OOPS) o posiblemente tener un impacto no especificado a través de un tamaño manipulado de la cabecera de partición EFI GUID en un medio extraíble.

It was discovered that KVM did not correctly initialize certain CPU registers. A local attacker could exploit this to crash the system, leading to a denial of service. Thomas Pollet discovered that the RDS network protocol did not check certain iovec buffers. A local attacker could exploit this to crash the system or possibly execute arbitrary code as the root user. Vasiliy Kulikov discovered that the Linux kernel X.25 implementation did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. Various other issues were also addressed.
