CVE-2024-20861

Memory corruption via unchecked use-after-free

Published May 7, 2024 · Updated Aug 1, 2024

Use after free in SveService on Samsung Mobile Devices before SMR May-2024 Release 1 allows local users to corrupt memory. SveService continues to access freed memory because its object-handling path omits the check needed to block reuse after release. The flaw affects Android 12 through 14 and requires elevated local privileges; the published consequence is memory corruption, not code execution.
