CVE-2014-1438 – kernel: x86: exceptions are not cleared in AMD FXSAVE workaround

https://notcve.org/view.php?id=CVE-2014-1438

The restore_fpu_checking function in arch/x86/include/asm/fpu-internal.h in the Linux kernel before 3.12.8 on the AMD K7 and K8 platforms does not clear pending exceptions before proceeding to an EMMS instruction, which allows local users to cause a denial of service (task kill) or possibly gain privileges via a crafted application. La función restore_fpu_checking en arch/x86/include/asm/fpu-internal.h en el kernel Linux anteriores a 3.12.8 en las plataformas AMD K7 y K8 no limpia las excepciones pendientes antes de proceder a una instrucción EMMS, lo cual permite a usuarios locales causar una denegación de servicio (task kill) o posiblemente obtener privilegios a través de una aplicación manipulada. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=26bef1318adc1b3a530ecc807ef99346db2aa8b0 http://lists.fedoraproject.org/pipermail/package-announce/2014-January/126858.html http://lists.fedoraproject.org/pipermail/package-announce/2014-January/126874.html http://www.halfdog.net/Security/2013/Vm86SyscallTaskSwitchKernelPanic http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.12.8 http://www.mandriva.com/security/advisories?name=MDVSA-2014:038 http://www.openwall.com/list • CWE-264: Permissions, Privileges, and Access Controls •
