CVE-2022-49650

The CVE-2022-49650 entry is a Linux kernel security fix for the dmaengine: qcom: bam_dma path. The root cause described is an unbalanced pm_runtime_get()/pm_runtime_put() when the BAM is controlled remotely, caused by a prior commit; the fix reverts that change and enables pm_runtime in all cases...

CVE-2022-49613 serial: 8250: Fix PM usage_count for console handover

In the Linux kernel, the following vulnerability has been resolved: serial: 8250: Fix PM usagecount for console handover When console is enabled, univ8250consolesetup calls serial8250consolesetup before .dev is set to uartport. Therefore, it will not call pmruntimegetsync. Later, when the actual...

CVE-2022-49427

The CVE pertains to the Linux kernel’s MTK IOMMU driver. After a patch (mtk_iommu_remove) removing clk_disable and relying on a runtime clock-control callback, the clock is now managed by runtime, eliminating the previous disable path. This addresses a warning trace seen when unbinding the MTK IO...
