CVE-2026-1095765.5 MED—
———The parser in PEAK-System PCAN driver correctly detected the malformed record, but the loop iterating the record list advanced its processed-bytes counter even when a record had been rejected as invalid.5hCVE-2026-1001348.8 ALT—
———Acrobat for Edge is affected by an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.7hCVE-2026-95109——
———The Cortex-A7 MMU Modules port validates a caller-supplied buffer by translating **one address** — the first byte. The common Module Manager hands its range check the module instance, the start address and the complete byte size; the Cortex-A7 implementation discarded the instance and the size and asked the MMU a single question about the start.
A memory-protected module therefore passed any range whose first byte was user-readable, however far the rest of it reached. Privileged dispatch code then read or wrote the whole range. Because every protected-module dispatcher that consumes a buffer or an extra-parameter array goes through this one macro, the defect is not in any individual service: it is in the primitive all of them rely on.7hCVE-2026-95107——
———A ThreadX module chooses `object_size` when it calls `txm_module_object_allocate`. The Module Manager adds its own 16-byte private header to that size and asked the object pool for the result **without checking the addition**. A size near the top of a `ULONG` wrapped, the pool served a block far smaller than the header, and the manager then wrote the header past the end of it and into the neighbouring byte-pool block.7hCVE-2026-93475——
———The X.509 parser in NetX Secure accepts an RSA public key of any size, but every signature-verification path decrypts into fixed-size buffers dimensioned for the `NX_CRYPTO_MAX_RSA_MODULUS_SIZE` default of 4096 bits. A certificate carrying a larger modulus drives an out-of-bounds write past a file-scope static during ordinary certificate-chain verification.
It is reachable pre-authentication. The issuer used for the crypto operation is looked up in the remote, peer-supplied store before the trusted store, so the attacker supplies the oversized key themselves as an intermediate in the chain they present. It triggers on a TLS or DTLS client verifying a malicious server's chain, and on a server performing client-certificate authentication.7hCVE-2026-1136797.0 ALT—
———HarfBuzz 8.0.0 through 14.6.0 contains an out-of-bounds write vulnerability in the experimental WebAssembly shaper because the font_glyph_to_string import has a wrong WAMR signature. Attackers can supply a crafted font whose wasm module places the output buffer near linear memory's end, writing glyph-name bytes into host memory to crash or corrupt applications.7h
