CVE-2010-3086

include/asm-x86/futex.h en el kernel de Linux anterior a v2.6.25 no aplica adecuadamente corrección de excepciones, lo que permite a usuarios locales causar una denegación de servicio (mediante un 'panic') a través de una solicitud válida que provoca un fallo de página.

Tavis Ormandy discovered that the Linux kernel did not properly implement exception fixup. A local attacker could exploit this to crash the kernel, leading to a denial of service. Dan Rosenberg discovered that the Linux kernel TIPC implementation contained multiple integer signedness errors. A local attacker could exploit this to gain root privileges. Dan Rosenberg discovered that the Linux kernel X.25 implementation incorrectly parsed facilities. A remote attacker could exploit this to crash the kernel, leading to a denial of service. 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. Vasiliy Kulikov discovered that the Linux kernel sockets implementation did not properly initialize certain structures. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. Nelson Elhage discovered that the Linux kernel IPv4 implementation did not properly audit certain bytecodes in netlink messages. A local attacker could exploit this to cause the kernel to hang, leading to a denial of service. Various other issues were also addressed.
