Sblim-sfcb: unsafe deserialization in sblim-sfcb provider-manager ipc allows out-of-bounds memory access via malformed operationhdr
Record summary
CVE-2026-73583 has a selected CVSS score of 6.6 (medium).
Description
A flaw was found in sblim-sfcb. A local attacker with access to the system can exploit an unsafe deserialization vulnerability in the provider-manager's inter-process communication (IPC) message parsing. By sending a specially crafted message, the attacker can cause out-of-bounds memory access, leading to the termination of the provider-manager process and a denial of service. This could also potentially result in limited unintended information disclosure.
