CVE-2020-0235 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. In crus_sp_shared_ioctl we first copy 4 bytes from userdata into "size" variable, and then use that variable as the size parameter for "copy_from_user", ending up overwriting memory following "crus_sp_hdr". "crus_sp_hdr" is a static variable, of type "struct crus_sp_ioctl_header".Product: AndroidVersions: Android kernelAndroid ID: A-135129430. EPSS estimates a 0.44% chance of exploitation in the next 30 days.
