During system suspend/resume, there exists a time window between: - suspend_noirq and the system entering suspend - the system starting to resume and resume_noirq In this window, the I2C controller resources such as clock and pinctrl may already be disabled or not yet restored. If a workqueue triggers an I2C transfer in this period, the driver attempts to access I2C registers while the hardware resources are unavailable, which may lead to system hang. Mark the I2C adapter as suspended during noirq suspend and block new transfers until resume, ensuring that I2C transfers are only issued when hardware resources are available. The Linux kernel CVE team has assigned CVE-2026-74462 to this issue. Affected and fixed versions =========================== Issue introduced in 6.14 with commit 358025ac091e5a54f9819b33ee9c7cb07c55ee5d and fixed in 6.18.44 with commit 7a5db225ab5a6b095f6c37197b3b114921d85541 Issue introduced in 6.14 with commit 358025ac091e5a54f9819b33ee9c7cb07c55ee5d and fixed in 7.1.8 with commit ec8e15e3e5c7e8180b13399f5a5aff8415bf16c5 Issue introduced in 6.14 with commit 358025ac091e5a54f9819b33ee9c7cb07c55ee5d and fixed in 7.2-rc6 with commit 00d86dd5c2034e0e139e4806137b3b43e07ddd83 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2026-74462 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/i2c/busses/i2c-imx.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/7a5db225ab5a6b095f6c37197b3b114921d85541 https://git.kernel.org/stable/c/ec8e15e3e5c7e8180b13399f5a5aff8415bf16c5 https://git.kernel.org/stable/c/00d86dd5c2034e0e139e4806137b3b43e07ddd83
