Descriptions
In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: oss: Fix races at processing SysEx messages OSS sequencer handles the SysEx messages split in 6 bytes packets, and
ALSA sequencer OSS layer tries to combine those. It stores the data
in the internal buffer and this access is racy as of now, which may
lead to the out-of-bounds access. As a temporary band-aid fix, introduce a mutex for serializing the
process of the SysEx message packets.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ALSA: seq: oss: Se corrigen las ejecuciones al procesar mensajes SysEx El secuenciador OSS maneja los mensajes SysEx divididos en paquetes de 6 bytes y la capa OSS del secuenciador ALSA intenta combinarlos. Almacena los datos en el búfer interno y este acceso es acelerado a partir de ahora, lo que puede llevar al acceso fuera de los límites. Como solución temporal, introduzca un mutex para serializar el proceso de los paquetes de mensajes SysEx.
