CVE-2024-46689

A flaw was found in the Linux kernel. Incorrect memory mapping of the cmd-db shared memory region as Write-Back (WB) instead of Write-Combine (WC) can lead to a Denial of Service (DoS). When a hypervisor other than the Qualcomm Hypervisor is in use, the eXtended Protection Unit (XPU) may falsely detect cache evictions as unauthorized writes, triggering a secure interrupt and an endless loop within the Trust Zone.
