UBUNTU-CVE-2022-50700

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

CVE-2022-50700 affects the Linux kernel WiFi driver ath10k on certain devices (WCN3990). The issue is a race where the host unmaps/frees the copy engine buffer before the hardware completes processing, causing an SMMU fault and potentially a kernel panic. The described workaround is to delay unma...
