CVE-2024-20887

Service interruption via unsafe Windows junction handling

Published Jun 4, 2024 · Updated Aug 1, 2024

Insecure junction handling in Samsung Galaxy Buds Manager before 2.1.240315.51 allows local users to create arbitrary directories. The PC build fails to reject a Windows junction or mount point that redirects a directory operation outside its intended location. Local access without prior privileges is sufficient, and successful exploitation interrupts availability rather than reading or modifying data.
