CVE-2022-36280

System crash via unchecked cursor copy dimensions

Published Sep 9, 2022 · Updated Sep 17, 2024

Out-of-bounds write in Linux Kernel 3.2-rc1 through 5.13.0-52 allows local users to crash the system via a crafted DMA surface copy. In vmw_kms_cursor_snoop, unchecked copy-box width or height lets memcpy copy an oversized VMware virtual GPU surface into the fixed-size snooped cursor image. Exploitation requires access to /dev/dri/card0 or /dev/dri/renderD128 and the ability to issue an ioctl; the bounded reported consequence is a system crash.
