Description
A flaw was found in the Linux kernel's bonding module. A local attacker could trigger a 'scheduling while atomic' bug by changing a bond's active slave. This occurs because the ipsec_lock is incorrectly implemented as a spin lock, which can lead to a system crash and result in a Denial of Service (DoS).
