Descriptions
Buffer overflow in the mp_override_legacy_irq() function in arch/x86/kernel/acpi/boot.c in the Linux kernel through 3.2 allows local users to gain privileges via a crafted ACPI table.
Desbordamiento de búfer en la función mp_override_legacy_irq() en arch/x86/kernel/acpi/boot.c en el kernel de Linux hasta la versión 3.2 permite que los usuarios locales obtengan privilegios mediante una tabla ACPI manipulada.
Buffer overflow in the mp_override_legacy_irq() function in arch/x86/kernel/acpi/boot.c in the Linux kernel through 4.12.2 allows local users to gain privileges via a crafted ACPI table.
Ralf Spenneberg discovered that the ext4 implementation in the Linux kernel did not properly validate meta block groups. An attacker with physical access could use this to specially craft an ext4 image that causes a denial of service. It was discovered that an information disclosure vulnerability existed in the ACPI implementation of the Linux kernel. A local attacker could use this to expose sensitive information. Various other issues were also addressed.
