Detailsinfo

A vulnerability was found in Qualcomm (unknown version) and classified as critical. This issue affects the function cam_mem_get_cpu_buf of the component Kernel API. The manipulation of the argument FastConnect 6800/FastConnect 6900/FastConnect 7800/QCA6391/QCA6426/QCA6436/QCN9074/QCS410/QCS610/SD865 5G/Snapdragon 8 Gen 1 Mobile Platform/Snapdragon 865 5G Mobile Platform/Snapdragon 865+ 5G Mobile Platform with an unknown input leads to a out-of-bounds vulnerability. Using CWE to declare the problem leads to CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The buffer obtained from kernel APIs such as cam_mem_get_cpu_buf() may be readable/writable in userspace after kernel accesses it. In other words, user mode may race and modify the packet header (e.g. header.count), causing checks (e.g. size checks) in kernel code to be invalid. This may lead to out-of-bounds read/write issues.

The weakness was released 08/08/2023. The advisory is shared at qualcomm.com. The identification of this vulnerability is CVE-2023-28576 since 03/17/2023. Technical details are known, but no exploit is available.

Upgrading eliminates this vulnerability.
