CVE-2026-115505libsmb2 before 6.3 contains integer overflow vulnerabilities in the DCE/RPC NDR decoder in lib/dcerpc.c that allow heap out-of-bounds reads and writes Executive summary The advisory says libsmb2 versions before 6.3 contain integer overflow flaws in the DCE/RPC data decoder that can let an attacker read and write memory outside the intended heap buffer. The advisory does not state a severity rating, and it does not describe a fix or workaround beyond the version threshold of 6.3. Technical summary The flaw is an integer overflow in the NDR decoder for DCE/RPC in lib/dcerpc.c, which the advisory says leads to heap out-of-bounds reads and writes. The advisory does not state the attack vector, required privileges or user interaction, or whether it is remotely exploitable. It states that versions before 6.3 are affected and implies 6.3 is fixed, but it does not explicitly name a fixed version string beyond that threshold. A CVSS score, workarounds, exploitation status, and detection guidance are not stated in the advisory. The repository text also describes libdcerpc as a separate library in the libdcerpc/ directory that is built by default on Linux. Summaries are generated by AI from the linked advisory text. Confirm versions and fixes at the source.
