CVE-2018-11246Network attack vector

Service interruption via unreleased process memory

Published Jan 11, 2021 · Updated Aug 5, 2024

Memory leak in K7TSMngr.exe in K7 Antivirus Premium 15.1.0.53 allows attackers to interrupt service through crafted internal-channel input. K7 identifies improper handling of that input but does not disclose which message or allocation path fails to release memory. Triggering requires access to an affected internal channel; published material limits the reported consequence to denial of service without specifying a hang or crash.
