No USB or network protocol message carries the trigger; this is a probe error-path leak.\nAC:H - After imx95_usb_phy_get_tca() succeeds, the only later failure is ENOMEM from kzalloc/devres_alloc in __devm_of_phy_provider_register(); imx8m_get_phy_tuning_data() cannot fail. That GFP_KERNEL failure is not attacker-controlled, and suppress_bind_attrs=true blocks sysfs rebind of imx8mq-usb-phy.\nPR:N - imx8mq_usb_phy_probe() has no capable() check. PHY_FSL_IMX8MQ_USB defaults y on ARCH_MXC&&ARM64, so of_platform populate binds usb3_phy@4c1f0040 during kernel init on i.MX95 boards that set status=okay. Sysfs bind is not required and is disabled by suppress_bind_attrs.\nUI:N - of_platform probe of usb3_phy and a later tcpci/tcpm_register_port() of ptn5110@50 (imx95-19x19-evk typec_con) run unattended at boot. typec_register_port() calls typec_switch_get() without a mount, open, or USB-C cable plug.\nS:U - The leaked typec_switch_dev, the devres free of imx8mq_usb_phy, and tca_blk_typec_switch_set() run in the host kernel PHY/Type-C stack. This is not a KVM/Xen guest-to-host escape or an IOMMU/DMA bypass.\nC:H - typec_switch_register() stores drvdata=imx_phy; probe failure then frees that imx8mq_usb_phy via devres while the class device remains. tca_blk_typec_switch_set() reads the freed object via typec_switch_get_drvdata() when TCPM's tcpm_mux_set() calls typec_set_orientation().\nI:H - The same dangling drvdata is used by tca_blk_typec_switch_set() to clk_prepare_enable(imx_phy->clk) and by tca_blk_orientation_set() to writel() TCA_GCFG/TCA_SYSMODE_CFG through tca->base; reclaiming the freed imx8mq_usb_phy/tca_blk slab is a write and control-flow primitive.\nA:H - Once probe fails, fwnode_typec_switch_get() does try_module_get(sw_dev->dev.parent->driver->owner) with parent->driver NULL, or tca_blk_typec_switch_set() dereferences the freed imx_phy; either path oopses the i.MX95 host."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/phy/freescale/phy-fsl-imx8mq-usb.c"], "versions": [{"version": "b58f0f86fd6156d7b084257f5c91ceaf7d760927", "lessThan": "f1b7b2c7ffa9711d1298f52790b377fe02efc1db", "status": "affected", "versionType": "git"}, {"version": "b58f0f86fd6156d7b084257f5c91ceaf7d760927", "lessThan": "84646f5b945a370f6999eed59a334387b0abc282", "status": "affected", "versionType": "git"}, {"version": "b58f0f86fd6156d7b084257f5c91ceaf7d760927", "lessThan": "87a1805b1c346b092c34f96f3806f207792910e1", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/phy/freescale/phy-fsl-imx8mq-usb.c"], "versions": [{"version": "6.15", "status": "affected"}, {"version": "0", "lessThan": "6.15", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.50", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2.4", "lessThanOrEqual": "7.2.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.3", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.15", "versionEndExcluding": "6.18.50"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.15", "versionEndExcluding": "7.2.4"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.15", "versionEndExcluding": "7.3"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/f1b7b2c7ffa9711d1298f52790b377fe02efc1db"}, {"url": "https://git.kernel.org/stable/c/84646f5b945a370f6999eed59a334387b0abc282"}, {"url": "https://git.kernel.org/stable/c/87a1805b1c346b092c34f96f3806f207792910e1"}], "title": "phy: fsl-imx8mq-usb: fix typec switch leak on probe error path", "x_generator": {"engine": "bippy-1.2.0"}}}}
