CVE-2010-4527
Published: 13 January 2011
The load_mixer_volumes function in sound/oss/soundcard.c in the OSS sound subsystem in the Linux kernel before 2.6.37 incorrectly expects that a certain name field ends with a '\0' character, which allows local users to conduct buffer overflow attacks and gain privileges, or possibly obtain sensitive information from kernel memory, via a SOUND_MIXER_SETLEVELS ioctl call.
From the Ubuntu Security Team
Dan Rosenberg discovered that the OSS subsystem did not handle name termination correctly. A local attacker could exploit this crash the system or gain root privileges.
