In the Linux kernel, the following vulnerability has been resolved: video: fbdev: sm712fb: Fix crash in smtcfb_write() When the sm712fb driver writes three bytes to the framebuffer, the driver will crash: BUG: unable to handle page fault for address:…
Does this matter?
Lower severity and a low EPSS score (0.29%). Track it; it rarely justifies an emergency change on its own.
