CVE-2024-47017

Local privilege escalation via freed stack reference

Published Oct 25, 2024 · Updated Oct 25, 2024

Use-after-free in ufshc_scsi_cmd in the Google Android kernel allows local users to elevate privileges through UFS command handling. The ufs.c routine uses a stack variable after it has been released while processing a SCSI command. Exploitation requires existing local access but no additional execution privileges or user interaction, and the published consequence is privilege elevation.
