CVE-2026-72007

/// Technical description

In the Linux kernel, the following vulnerability has been resolved:

pmdomain: imx: Fix i.MX8MP VC8000E power up sequence

Per errata[1]:

ERR050531: VPU_NOC power down handshake may hang during VC8000E/VPUMIX

power up/down cycling.

Description: VC8000E reset de-assertion edge and AXI clock may have a

timing issue.

Workaround: Set bit2 (vc8000e_clk_en) of BLK_CLK_EN_CSR to 0 to gate off

both AXI clock and VC8000E clock sent to VC8000E and AXI clock sent to

VPU_NOC m_v_2 interface during VC8000E power up(VC8000E reset is

de-asserted by HW)

Add a bool variable is_errata_err050531 in

'struct imx8m_blk_ctrl_domain_data' to represent whether the workaround

is needed. If is_errata_err050531 is true, first clear the clk before

powering up gpc, then enable the clk after powering up gpc.

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
