Detailsinfo

A vulnerability was found in Linux Kernel up to 6.1.161/6.6.121/6.12.67/6.18.7. It has been declared as critical. Affected by this vulnerability is the function imx8mq_vpu_power_notifier of the component pmdomain. The impact remains unknown. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: pmdomain: imx8m-blk-ctrl: Remove separate rst and clk mask for 8mq vpu For i.MX8MQ platform, the ADB in the VPUMIX domain has no separate reset and clock enable bits, but is ungated and reset together with the VPUs. So we can't reset G1 or G2 separately, it may led to the system hang. Remove rst_mask and clk_mask of imx8mq_vpu_blk_ctl_domain_data. Let imx8mq_vpu_power_notifier() do really vpu reset.
