Description

The bnep_sock_ioctl function in net/bluetooth/bnep/sock.c in the Linux kernel before 2.6.39 does not ensure that a certain device field ends with a '\0' character, which allows local users to obtain potentially sensitive information from kernel stack memory, or cause a denial of service (BUG and system crash), via a BNEPCONNADD command.

Affected products

Linux kernel: through 2.6.38.8; 2.6.38, 2.6.38-rc1, 2.6.38-rc2, 2.6.38-rc3, 2.6.38-rc4, 2.6.38-rc5 (+10)
