CVE-2010-4529

Published: 13 January 2011

Integer underflow in the irda_getsockopt function in net/irda/af_irda.c in the Linux kernel before 2.6.37 on platforms other than x86 allows local users to obtain potentially sensitive information from kernel heap memory via an IRLMP_ENUMDEVICES getsockopt call.

From the Ubuntu security team

Dan Rosenberg discovered that IRDA did not correctly check the size of buffers. On non-x86 systems, a local attacker could exploit this to read kernel heap memory, leading to a loss of privacy.
