Affected is an unknown functionality of the component HLOS. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Memory corruption due to buffer copy without checking the size of input in HLOS when input message size is larger than the buffer capacity.

The weakness was shared 03/11/2023. The advisory is shared for download at qualcomm.com. This vulnerability is traded as CVE-2022-33278 since 06/14/2022. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $5k-$25k (estimation calculated on 09/03/2025).
