CVE-2010-2954

Published: 3 September 2010

The irda_bind function in net/irda/af_irda.c in the Linux kernel before 2.6.36-rc3-next-20100901 does not properly handle failure of the irda_open_tsap function, which allows local users to cause a denial of service (NULL pointer dereference and panic) and possibly have unspecified other impact via multiple unsuccessful calls to bind on an AF_IRDA (aka PF_IRDA) socket.

From the Ubuntu Security Team

Tavis Ormandy discovered that the IRDA subsystem did not correctly shut down. A local attacker could exploit this to cause the system to crash or possibly gain root privileges.
