The arm platform-specific code uses a signed integer comparison when validating system call numbers. An attacker who has obtained code execution within a user thread is able to elevate privileges to that of the kernel. See NCC-ZEP-001 This issue affects: zephyrproject-rtos zephyr version 1.14.0 and later versions. version 2.1.0 and later versions.

The shell subsystem contains a buffer overflow, whereby an adversary with physical access to the device is able to cause a memory corruption, resulting in denial of service or possibly code execution within the Zephyr kernel. See NCC-NCC-019 This issue affects: zephyrproject-rtos zephyr version 1.14.0 and later versions. version 2.1.0 and later versions.

A malformed JSON payload that is received from an UpdateHub server may trigger memory corruption in the Zephyr OS. This could result in a denial of service in the best case, or code execution in the worst case. See NCC-NCC-016 This issue affects: zephyrproject-rtos zephyr version 2.1.0 and later versions. version 2.2.0 and later versions.

Out-of-bounds Write in the USB Mass Storage memoryWrite handler with unaligned Sizes See NCC-ZEP-024, NCC-ZEP-025, NCC-ZEP-026 This issue affects: zephyrproject-rtos zephyr version 1.14.1 and later versions. version 2.1.0 and later versions.

** REJECT ** Number assigned to issue that does not qualify for a CVE.

An elevation of privilege vulnerability exists when the MpSigStub.exe for Defender allows file deletion in arbitrary locations.To exploit the vulnerability, an attacker would first have to log on to the system, aka 'Microsoft Defender Elevation of Privilege Vulnerability'.

USB DFU has a potential buffer overflow where the requested length (wLength) is not checked against the buffer size. This could be used by a malicious USB host to exploit the buffer overflow. See NCC-ZEP-002 This issue affects: zephyrproject-rtos zephyr version 1.14.1 and later versions. version 2.1.0 and later versions.

WebKitGTK through 2.26.4 and WPE WebKit through 2.26.4 (which are the versions right before 2.28.0) contains a memory corruption issue (use-after-free) that may lead to arbitrary code execution. This issue has been fixed in 2.28.0 with improved memory handling.
