Details

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
