Title
Infinite decoding loop through specially crafted payload
Summary
The Candid library causes a Denial of Service while parsing a specially crafted payload with 'empty' data type. For example, if the payload is `record { * ; empty }` and the canister interface expects `record { * }` then the Rust candid decoder treats empty as an extra field required by the type. The problem with the type empty is that the candid Rust library wrongly categorizes empty as a recoverable error when skipping the field and thus causing an infinite decoding loop. Canisters using affected versions of candid are exposed to denial of service by causing the decoding to run indefinitely until the canister traps due to reaching maximum instruction limit per execution round. Repeated exposure to the payload will result in degraded performance of the canister. Note: Canisters written in Motoko are unaffected.

CVE-2023-4010 (GCVE-0-2023-4010)

Vulnerability from cvelistv5 – Published: 2023-07-31 16:22 – Updated: 2026-02-18 17:14

Title
Kernel: usb: hcd: malformed usb descriptor leads to infinite loop in usb_giveback_urb()
Summary
A flaw was found in the USB Host Controller Driver framework in the Linux kernel. The usb_giveback_urb function has a logic loophole in its implementation. Due to the inappropriate judgment condition of the goto statement, the function cannot return under the input of a specific malformed descriptor file, so it falls into an endless loop, resulting in a denial of service.

CVE-2023-3748 (GCVE-0-2023-3748)

Vulnerability from cvelistv5 – Published: 2023-07-24 15:19 – Updated: 2024-09-27 13:44

Title
Inifinite loop in babld message parsing may cause dos
Summary
A flaw was found in FRRouting when parsing certain babeld unicast hello messages that are intended to be ignored. This issue may allow an attacker to send specially crafted hello messages with the unicast flag set, the interval field set to 0, or any TLV that contains a sub-TLV with the Mandatory flag set to enter an infinite loop and cause a denial of service.

CVE-2023-3255 (GCVE-0-2023-3255)

Title
Qemu: vnc: infinite loop in inflate_buffer() leads to denial of service
Summary
A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. A wrong exit condition may lead to an infinite loop when inflating an attacker controlled zlib buffer in the `inflate_buffer` function. This could allow a remote authenticated client who is able to send a clipboard to the VNC server to trigger a denial of service.
