Summary
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: 96000004 [#1] PREEMPT_RT SMP
