Description
In the Linux kernel, the following vulnerability has been resolved: soc: qcom: qmi_encdec: Restrict string length in decode The QMI TLV value for strings in a lot of qmi element info structures account for null terminated strings with MAX_LEN + 1. If a string is actually MAX_LEN + 1 length, this will cause an out of bounds access when the NULL character is appended in decoding.

Executive Summary

This vulnerability in the Linux kernel's Qualcomm QMI encoder/decoder (qmi_encdec) involves improper handling of string lengths during decoding. Specifically, the QMI TLV value for strings assumes null-terminated strings with a maximum length plus one character. If a string actually reaches this maximum length plus one, appending the null terminator causes an out-of-bounds memory access, potentially leading to memory corruption or crashes.

Impact Analysis

The vulnerability can lead to out-of-bounds memory access when decoding certain strings, which may cause system instability, crashes, or potentially allow an attacker to execute arbitrary code or cause denial of service on affected systems using the vulnerable Linux kernel component.
