CVE-2011-2492 (retired)

Priority
Description
The bluetooth subsystem in the Linux kernel before 3.0-rc4 does not
properly initialize certain data structures, which allows local users to
obtain potentially sensitive information from kernel memory via a crafted
getsockopt system call, related to (1) the l2cap_sock_getsockopt_old
function in net/bluetooth/l2cap_sock.c and (2) the
rfcomm_sock_getsockopt_old function in net/bluetooth/rfcomm/sock.c.
Ubuntu-Description
It was discovered that Bluetooth l2cap and rfcomm did not correctly
initialize structures. A local attacker could exploit this to read portions
of the kernel stack, leading to a loss of privacy.
