CVE-2026-102730 (GCVE-0-2026-102730)

Vulnerability from cvelistv5 – Published: 2026-09-29 17:59 – Updated: 2026-09-29 18:25
VLAI
Summary
Mounting an attacker-controlled NAND flash image (`lx_nand_flash_open()`) triggers an unbounded out-of-bounds heap **write** in LevelX's NAND flash-translation-layer metadata parser that overwrites a driver function pointer in the control block, giving a demonstrated control-flow hijack — RIP set to a full 8-byte attacker-chosen value (register-verified). Two accompanying OOB reads. All reproduced verbatim under ASan at HEAD `9f1cfdc`. (The affected metadata-parser header states "Some portions generated by Copilot (Sonnet 4.6)" — an AI-generated parser with an unchecked on-flash count.)

CVE-2026-102711 (GCVE-0-2026-102711)

Vulnerability from cvelistv5 – Published: 2026-09-29 17:38 – Updated: 2026-09-29 21:01
VLAI
Summary
Two issues in the ThreadX loadable-module loader, reached when a device loads an attacker-controlled module object via `_txm_module_manager_memory_load` / `_txm_module_manager_in_place_load` — APIs that take ONLY a base pointer, no image length, so every size/offset field in `TXM_MODULE_PREAMBLE` is fully attacker-trusted: (1) a heap OOB **read** (`code_size` trusted as the source-image length in the code-copy loop), and (2) a control-flow-integrity / defense-in-depth gap (module entry/start/callback/stop pointers computed as `code_start + preamble_offset` with only a `!= 0` check, and the preamble `checksum` never verified). No controlled OOB write was found (honest — the copy destination is overflow-guarded).

Title
Kiteworks Core Improper Validation of Specified Quantity in Input
Summary
Kiteworks did not enforce the maximum permitted value for a configurable security-policy setting. An authenticated administrator could set this value outside its intended range so that the associated control never activated, while the control continued to appear enabled in the administrative interface and audit log, allowing it to be silently rendered ineffective.

CVE-2026-97058 (GCVE-0-2026-97058)

Vulnerability from cvelistv5 – Published: 2026-09-24 13:51 – Updated: 2026-09-24 14:32

Title
sprintf-js through 1.1.3 Denial of Service via Unbounded Precision
Summary
sprintf-js through 1.1.3 passes unbounded precision specifiers to toFixed, toExponential, and toPrecision methods without validation, causing uncaught RangeError exceptions. Attackers who control format strings can inject precision values exceeding ECMAScript limits to abort calling operations with minimal payload.

CVE-2026-97057 (GCVE-0-2026-97057)

Title
redis-parser through 3.0.0 Denial of Service via Invalid Array Length
Summary
redis-parser through 3.0.0 fails to validate the multi-bulk length value in RESP protocol parsing, allowing attackers to trigger an uncaught RangeError by supplying an excessively large declared length. A malicious or compromised Redis endpoint can deliver a crafted RESP header with a length above 2^32-1 to crash the Node.js client process.

Mitigation MIT-5
Implementation

Strategy: Input Validation

  • Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
  • When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
  • Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
