CVE-2010-4527 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.49% chance of exploitation in the next 30 days.
