Applicable for: Wind River Linux LTS 23
Component/s: Kernel
In the Linux kernel, the following vulnerability has been resolved:EOL][EOL]drm/exynos: exynos7_drm_decon: add vblank check in IRQ handling[EOL][EOL]If there's support for another console device (such as a TTY serial),[EOL]the kernel occasionally panics during boot. The panic message and a[EOL]relevant snippet of the call stack is as follows:[EOL][EOL] Unable to handle kernel NULL pointer dereference at virtual address 000000000000000[EOL] Call trace:[EOL] drm_crtc_handle_vblank+0x10/0x30 (P)[EOL] decon_irq_handler+0x88/0xb4[EOL] [...][EOL][EOL]Otherwise, the panics don't happen. This indicates that it's some sort[EOL]of race condition.[EOL][EOL]Add a check to validate if the drm device can handle vblanks before[EOL]calling drm_crtc_handle_vblank() to avoid this.
