CVE-2026-5031

A vulnerability in the Poly Lens Desktop application running on the Windows platform might allow modifications to the filesystem, which might lead to SYSTEM level privileges being granted.

A vulnerability was found in SourceCodester Train Scheduler App 1.0 and classified as critical. Affected by this issue is some unknown functionality of the file /train_scheduler_app/?action=delete. The manipulation of the argument id leads to improper control of resource identifiers. The attack may be launched remotely. The identifier of this vulnerability is VDB-212504.

A vulnerability classified as critical was found in School Club Application System 1.0. This vulnerability affects a request to the file /scas/classes/Users.php?f=save_user. The manipulation with a POST request leads to privilege escalation. The attack can be initiated remotely and does not require authentication. The exploit has been disclosed to the public and may be used.

OP-TEE is a Trusted Execution Environment (TEE) designed as companion to a non-secure Linux kernel running on Arm; Cortex-A cores using the TrustZone technology. Starting in version 4.3.0 and prior to version 4.11.0, a type confusion vulnerability exists in OP-TEE OS when processing an FFA_MEM_SHARE request from the normal world. This only applies when OP-TEE is configured as an SPMC for S-EL0 SPs, that is, with `CFG_CORE_SEL1_SPMC=y` and `CFG_SECURE_PARTITION=y`. Version 4.11.0 fixes the issue.

OP-TEE is a Trusted Execution Environment (TEE) designed as companion to a non-secure Linux kernel running on Arm; Cortex-A cores using the TrustZone technology. Prior to version 4.11.0, on many of the ECDH shared secret paths, the public key isn't verified to be a point on the correct curve. By passing approximately 30-40 crafted public keys to OP-TEE, the private key can be reconstructed by a normal world attacker. When calling TEE_DeriveKey the public key is provided with full X and Y values, but the (X, Y) point might not satisfy the `Y^2 == X^3 + aX + b mod P` math for the specific curve that is used. When those public keys aren't rejected, the attacker can select public keys such that each DeriveKey call will leak `d % r` where `d` is the private key and `r` comes from the relationship between the correct curve and the attacker selected curve. With enough leaked data the Chinese remainder theorem can be used to recover the full private key. Version 4.11.0 fixes the issue.

daphne before 4.2.2 did not pass maxFramePayloadSize or maxMessagePayloadSize to Autobahn's WebSocketServerFactory. Because Autobahn defaults both values to 0 (unlimited), an unauthenticated remote attacker could send arbitrarily large WebSocket messages or frames, causing excessive memory consumption and a denial of service.
