CVSS v3.1
Official Description
Floating point information leak in the context switch code for Linux 2.4.x only checks the MFH bit but does not verify the FPH owner, which allows local users to read register values of other processes by setting the MFH bit.
Technical Analysis
CVE-2004-0565 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
