In the Linux kernel, the following vulnerability has been resolved:
drm/bridge: adv7511: fix crash on irq during probe Moved IRQ registration
down to end of adv7511_probe(). If an IRQ already is pending during
adv7511_probe (before adv7511_cec_init) then cec_received_msg_ts could
crash using uninitialized data: Unable to handle kernel read from
unreadable memory at virtual address 00000000000003d5 Internal error: Oops:
