CVE-2008-3272

Publication date 8 August 2008

Last updated 24 July 2024

The snd_seq_oss_synth_make_info function in sound/core/seq/oss/seq_oss_synth.c in the sound subsystem in the Linux kernel before 2.6.27-rc2 does not verify that the device number is within the range defined by max_synthdev before returning certain data to the caller, which allows local users to obtain sensitive information.

From the Ubuntu Security Team

Tobias Klein discovered that the OSS interface through ALSA did not correctly validate the device number. A local attacker could exploit this to access sensitive kernel memory, leading to a denial of service or a loss of privacy.
