Summary
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: ffffc90001ffffff RIP: 0010:smtcfb_write+0x454/0x5b0 Call Trace: vfs_write+0x291/0xd60 ? do_sys_openat2+0x27d/0x350 ? __fget_light+0x54/0x340 ksys_write+0xce/0x190 do_syscall_64+0x43/0x90 entry_SYSCALL_64_after_hwframe+0x44/0xae Fix it by removing the open-coded endianness fixup-code.
