Descriptions
An issue where a provided address with access_ok() is not checked was discovered in i915_gem_execbuffer2_ioctl in drivers/gpu/drm/i915/i915_gem_execbuffer.c in the Linux kernel through 4.19.13. A local attacker can craft a malicious IOCTL function call to overwrite arbitrary kernel memory, resulting in a Denial of Service or privilege escalation.
Se ha descubierto un problema por el cual una dirección proporcionada con access_ok() no se comprueba en i915_gem_execbuffer2_ioctl en drivers/gpu/drm/i915/i915_gem_execbuffer.c en el kernel de Linux hasta la versión 4.19.13. Un atacante local puede manipular una llamada de función IOCTL para sobrescribir memoria arbitraria del kernel, lo que resulta en una denegación de servicio (DoS) o el escalado de privilegios.
Timothy Michaud discovered that the i915 graphics driver in the Linux kernel did not properly validate user memory locations for the i915_gem_execbuffer2_ioctl. A local attacker could possibly use this to cause a denial of service or execute arbitrary code. It was discovered that the Kvaser CAN/USB driver in the Linux kernel did not properly initialize memory in certain situations. A local attacker could possibly use this to expose sensitive information. Various other issues were also addressed.
