CVE-2026-104592 Details
Description
libosmocore through 1.14.1 contains an out-of-bounds read in the CBSP WRITE-REPLACE decoder in src/gsm/cbsp.c. This allows a remote attacker to cause a denial of service.
A stack-based out-of-bounds read vulnerability has been identified in libosmocore versions through 1.14.1. The issue arises in the Cell Broadcast Service Protocol (CBSP) WRITE-REPLACE decoder, where the decoder improperly handles the page count received over the wire. This flaw allows a remote attacker to read memory beyond the intended bounds, potentially leading to a denial-of-service condition.
Users can upgrade to libosmocore version 1.14.2, which addresses this vulnerability by adding proper bounds checking on the page count before processing the message.
