Linux Kernel up to 7.2-rc3 pmdomain denial of service

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability classified as problematic has been found in Linux Kernel up to 6.6.144/6.12.96/6.18.39/7.1.4/7.2-rc3. This affects an unknown function of the component pmdomain. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on availability. The summary by CVE is:

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. [1] https://www.nxp.com/webapp/Download?colCode=IMX8MP_1P33A

It is possible to read the advisory at git.kernel.org. This vulnerability is uniquely identified as CVE-2026-72007 since 08/09/2026. The exploitability is told to be easy. Attacking locally is a requirement. The exploitation needs additional levels of successful authentication. The technical details are unknown and an exploit is not publicly available.
