[PATCH v2] optionrom: disallow int19 redirect for pnp roms.
by Gerd Hoffmann May 20, 2019

May 20, 2019

Check whenever pnp roms attempt to redirect int19, and in case it does log a message and undo the redirect. A pnp rom should not need this, we have BEVs and BCVs for that. Nevertheless there are roms in the wild which are redirecting int19. At least some BIOS implementations for physical hardware have a config option in the setup to allow/disallow int19 redirections, so just not allowing this seems to be the way to deal with this situation.

Possible security issue or intended functionality?
by k4m1 March 31, 2019

March 31, 2019

Hi, I noticed, that both bootloader - and kernel code are able to make BIOS ROM section writable again. This allows hostile code to make modifications to ROM contents, and then run the modified code. This may allow malicious code to gain privilege escalation from ring0 to ring -2 if I have not misunderstood this. Care to verify wheter this is an issue or not? - k4m1

Siabios did not boot debian from USB flash.

Siabios did not boot debian from USB flash. Booting from the hard disk is normal. What siabios settings can affect this behavior? USB boot flash file system is FAT32.

Seabios freezes (hangs) on "Press ESC for boot menu". Does not respond to the keyboard and does not boot from the sata disk. Last post code 0x7b. Console (full) output in putty_atomC3538.log. Coreboot 4.9 cfg in coreboot.config. Seabios config in seabios.config.
