4 | Subject: [PATCH] commands/ls: Require device_name is not NULL before printing | ||
5 | |||
6 | This can be triggered with: | ||
7 | ls -l (0 0*) | ||
8 | and causes a NULL deref in grub_normal_print_device_info(). | ||
9 | |||
10 | I'm not sure if there's any implication with the IEEE 1275 platform. | ||
