Details

In the Linux kernel, the following vulnerability has been resolved:

mlxbfgige: call requestirq() after NAPI initialized

The mlxbfgige driver encounters a NULL pointer exception in mlxbfgigeopen() when kdump is enabled. The sequence to reproduce the exception is as follows: a) enable kdump b) trigger kdump via "echo c > /proc/sysrq-trigger" c) kdump kernel executes d) kdump kernel loads mlxbfgige module e) the mlxbfgige module runs its open() as the the "oobnet0" interface is brought up f) mlxbf_gige module will experience an exception during its open(), something like:

The exception happens because there is a pending RX interrupt before the call to requestirq(RX IRQ) executes. Then, the RX IRQ handler fires immediately after this requestirq() completes. The ---truncated---
