CVE-2011-2700

Published: 06 September 2011

Multiple buffer overflows in the si4713_write_econtrol_string function in drivers/media/radio/si4713-i2c.c in the Linux kernel before 2.6.39.4 on the N900 platform might allow local users to cause a denial of service or have unspecified other impact via a crafted s_ext_ctrls operation with a (1) V4L2_CID_RDS_TX_PS_NAME or (2) V4L2_CID_RDS_TX_RADIO_TEXT control ID.

From the Ubuntu security team

Mauro Carvalho Chehab discovered that the si4713 radio driver did not correctly check the length of memory copies. If this hardware was available, a local attacker could exploit this to crash the system or gain root privileges.
