Atmel Advanced Software Framework (ASF) 4 has an Integer Overflow.

An issue was discovered in picoTCP 1.7.0. The code for processing the IPv6 headers does not validate whether the IPv6 payload length field is equal to the actual size of the payload, which leads to an Out-of-Bounds read during the ICMPv6 checksum calculation, resulting in either Denial-of-Service or Information Disclosure. This affects picoipv6extensionheaders and picochecksumadder (in picoipv6.c and picoframe.c).

A privilege escalation vulnerability in Microchip IStaX allows an authenticated low-privileged user to recover a shared per-device cookie secret from their own webstaxauth session cookie and forge a new cookie with administrative privileges.This issue affects IStaX before 2026.03.

The Microchip RN4870 module firmware 1.43 (and the Microchip PIC LightBlue Explorer Demo 4.2 DT100112) mishandles reject messages.

Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in Microchip TimeProvider 4100 (banner config modules) allows Cross-Site Scripting (XSS).This issue affects TimeProvider 4100: from 1.0 before 2.4.7.

Symmetricom SyncServer S100 2.90.70.3, S200 1.30, S250 1.25, S300 2.65.0, and S350 2.80.1 devices mishandle session validation, leading to unauthenticated creation, modification, or elimination of users.

In version 6.5 of Microchip MiWi software and all previous versions including legacy products, there is a possibility of frame counters being validated/updated prior to the message authentication. With this vulnerability in place, an attacker may increment the incoming frame counter values by injecting messages with a sufficiently large frame counter value and invalid payload. This results in denial of service/valid packets in the network. There is also a possibility of a replay attack in the stack.

In version 6.5 Microchip MiWi software and all previous versions including legacy products, the stack is validating only two out of four Message Integrity Check (MIC) bytes.

CMAC verification functionality in Microchip Atmel ATSAMA5 products is vulnerable to vulnerable to timing and power analysis attacks.

Microchip Atmel ATSAMA5 products in Secure Mode allow an attacker to bypass existing security mechanisms related to applet handling.

The Secure Monitor in Microchip Atmel ATSAMA5 products use a hardcoded key to encrypt and authenticate secure applets.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Microchip Time Provider 4100 allows SQL Injection.This issue affects Time Provider 4100: before 2.5.

If a SCSI READ(10) command is initiated via USB using the largest LBA (0xFFFFFFFF) with it's default block size of 512 and a count of 1,

the first 512 byte of the 0x80000000 memory area is returned to the user. If the block count is increased, the full RAM can be exposed.

The same method works to write to this memory area. If RAM contains pointers, those can be - depending on the application - overwritten to

return data from any other offset including Progam and Boot Flash.
