CVE-2013-1943 – kernel: kvm: missing check in kvm_set_memory_region()
https://notcve.org/view.php?id=CVE-2013-1943
The KVM subsystem in the Linux kernel before 3.0 does not check whether kernel addresses are specified during allocation of memory slots for use in a guest's physical address space, which allows local users to gain privileges or obtain sensitive information from kernel memory via a crafted application, related to arch/x86/kvm/paging_tmpl.h and virt/kvm/kvm_main.c. El subsistema KVM en el kernel de Linux anterior a v3.0 no comprueba si las direcciones del núcleo se especifican durante la asignación de slots de memoria para su uso en el espacio de direcciones físicas huesped, permitiendo a usuarios locales conseguir privilegios u obtener información confidencial de la memoria del núcleo a través de una aplicación especialmente diseñada, relacionada con arch/x86/kvm/paging_tmpl.h y virt/kvm/kvm_main.c. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=fa3d315a4ce2c0891cdde262562e710d95fba19e http://web.archive.org/web/20130329070349/http://ftp.osuosl.org/pub/linux/kernel/v3.0/ChangeLog-3.0 http://www.ubuntu.com/usn/USN-1939-1 https://bugzilla.redhat.com/show_bug.cgi?id=950490 https://github.com/torvalds/linux/commit/fa3d315a4ce2c0891cdde262562e710d95fba19e https://access.redhat.com/security/cve/CVE-2013-1943 • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2011-4098
https://notcve.org/view.php?id=CVE-2011-4098
The fallocate implementation in the GFS2 filesystem in the Linux kernel before 3.2 relies on the page cache, which might allow local users to cause a denial of service by preallocating blocks in certain situations involving insufficient memory. La implementación de fallocate en el sistema de ficheros GFS2 de los kernel Linux anteriores a v3.2 confía en la caché, pudiendo permitir a usuarios locales provocar una denegación de servicio mediante la pre-asignación de bloques que suponen ciertas situaciones de memoria insuficiente. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=64dd153c83743af81f20924c6343652d731eeecb http://www.kernel.org/pub/linux/kernel/v3.x/patch-3.2.bz2 https://github.com/torvalds/linux/commit/64dd153c83743af81f20924c6343652d731eeecb https://oss.oracle.com/git/?p=redpatch.git%3Ba=commit%3Bh=fadca7bdc43b02f518585d9547019966415cadfd https://www.redhat.com/archives/cluster-devel/2011-September/msg00064.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2013-2852 – Linux Kernel 3.3.5 - 'b43' Wireless Driver Privilege Escalation
