In the function grub_netbsd_setup_video(), struct grub_netbsd_btinfo_framebuf

reserved[16] isn't set to any values and is instead filled with junk data from
the stack. We can prevent this by setting params to {0}.Fixes: CID 375026 Signed-off-by: Alec Brown <[email protected]> --- grub-core/loader/i386/bsd.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/grub-core/loader/i386/bsd.c b/grub-core/loader/i386/bsd.c index 5f3290ce1..de63ca8dc 100644 --- a/grub-core/loader/i386/bsd.c +++ b/grub-core/loader/i386/bsd.c @@ -929,7 +929,7 @@ grub_netbsd_setup_video (void) struct grub_video_mode_info mode_info; void *framebuffer; const char *modevar; - struct grub_netbsd_btinfo_framebuf params; + struct grub_netbsd_btinfo_framebuf params = {0}; grub_err_t err; grub_video_driver_id_t driv_id; -- 2.27.0 _______________________________________________ Grub-devel mailing list [email protected] https://lists.gnu.org/mailman/listinfo/grub-devel
