CAIBA: Multicast Source Authentication for CAN through Reactive Bit Flipping

Controller Area Networks CANs are the backbone for reliable intra-vehicular communication. Recent cyberattacks have, however, exposed the weaknesses of CAN, which was designed without any security considerations in the 1980s. Current efforts to retrofit security via intrusion detection or message...

In the Linux kernel, the following vulnerability has been resolved: can: j1939: fix errant WARNONONCE in j1939sessiondeactivate The conclusion "j1939sessiondeactivate should be called with a session ref-count of at least 2" is incorrect. In some concurrent scenarios, j1939sessiondeactivate can be...

kernel: can: bcm: Fix UAF in bcm_proc_show()

A flaw was found in the Linux kernel's Controller Area Network CAN Broadcast Manager BCM module. A local attacker with low privileges could exploit a use-after-free vulnerability in the bcmprocshow function. This occurs because the bcmop object is freed before its corresponding procfs entry is...
