Nullptr dereference when a null char is present in a proto symbol. The symbol is parsed incorrectly, leading to an unchecked call into the proto file's name during generation of the resulting error message. Since the symbol is incorrectly parsed, the file is nullptr. We recommend upgrading to version 3.15.0 or greater.

CVE-2021-22570 [MEDIUM] CWE-476 protobuf: Incorrect parsing of nullchar in the proto symbol leads to Nullptr dereference
protobuf: Incorrect parsing of nullchar in the proto symbol leads to Nullptr dereference
Nullptr dereference when a null char is present in a proto symbol. The symbol is parsed incorrectly, leading to an unchecked call into the proto file's name during generation of the resulting error message. Since the symbol is incorrectly parsed, the file is nullptr. We recommend upgrading to version 3.15.0 or greater.
A flaw was found in protobuf. The vulnerability occurs due to incorrect parsing of a NULL character in the proto symbol and leads to a Null pointer dereference. This flaw allows an attacker to execute unauthorized code or commands, read memory, modify memory.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.

Withdrawn Advisory: NULL Pointer Dereference in Protocol Buffers
### Withdrawn Advisory
This advisory has been withdrawn because the protobuf vulnerability comes from the compiler rather that the code. This link is maintained to preserve external references.
### Original Description
Nullptr dereference when a null char is present in a proto symbol. The symbol is parsed incorrectly, leading to an unchecked call into the proto file's name during generation of the resulting error message. Since the symbol is incorrectly parsed, the file is nullptr. We recommend upgrading to version 3.15.0 or greater.
