n 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.

Summary
  • (es) 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 gestiona 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.
