In the Linux kernel, the following vulnerability has been resolved: wifi: ath10k: Delay the unmapping of the buffer On WCN3990, we are seeing a rare scenario where copy engine hardware is sending a copy complete interrupt to the host driver while still processing the buffer that the driver has...

CVE-2022-50700

Summary : CVE-2022-50700 affects the Linux kernel wifi driver (ath10k) on certain Qualcomm WCN3990 hardware. The issue occurs when the copy engine completes a DMA buffer and the host driver unmaps/frees the buffer while hardware may still access it, triggering an SMMU fault and potential kernel p...
