Description
The console selection feature in the Linux kernel 2.6.28 before 2.6.28.4, 2.6.25, and possibly earlier versions, when the UTF-8 console is used, allows physically proximate attackers to cause a denial of service (memory corruption) by selecting a small number of 3-byte UTF-8 characters, which triggers an "off-by-two memory error." NOTE: it is not clear whether this issue crosses privilege boundaries.
Metrics
NVD enrichment efforts reference publicly available information to associate
vector strings. CVSS information contributed by other sources is also
displayed.

La funcionalidad de selección de consola en el kernel de Linux 2.6.28 en versiones anteriores a 2.6.28.4, 2.6.25 y posiblemente versiones anteriores, cuando se utiliza la consola UTF-8, permite a atacantes físicamente próximos causar una denegación de servicio (corrupción de memoria) seleccionando un número pequeño de carácteres de 3 bytes UTF-8, lo que desencadena un "error de memoria off-by-two". NOTA: no queda claro si el problema traspasa límites de privilegio.
