CVE-2024-26876
Full vulnerability record from the local CVENow database.
Description
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 Call trace: cec_received_msg_ts+0x48/0x990 [cec] adv7511_cec_irq_process+0x1cc/0x308 [adv7511] adv7511_irq_process+0xd8/0x120 [adv7511] adv7511_irq_handler+0x1c/0x30 [adv7511] irq_thread_fn+0x30/0xa0 irq_thread+0x14c/0x238 kthread+0x190/0x1a8
