CVE-2003-0699
The C-Media PCI sound driver in Linux before 2.4.21 does not use the get_user function to access userspace, which crosses security boundaries and may facilitate the exploitation of vulnerabilities, a different vulnerability than CVE-2003-0700.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.96%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
