That matches other USB/UDC teardown UAFs scored Local and is higher severity than Physical.\nAC:L - A USB PD Hard Reset SIG_RX IRQ schedules reset_work, then pdphy_stop() only disable_irq() without cancel_work_sync, so the attacker can queue the work and immediately unbind/rebind until the worker runs on the freed pmic_typec_pdphy; such attacker-driven UAF races score AC:L.\nPR:L - Per CNA driver-removal UAF precedent, an unprivileged local user on Qualcomm phones, laptops, and automotive systems using this PMIC Type-C controller can spray the freed pmic_typec_pdphy while privileged or automated teardown proceeds; init-namespace root is not required for the UAF itself.\nUI:N - The attacker queues reset_work from in-flight SIG_RX and initiates driver removal themselves; no separate victim action such as plugging a USB cable, mounting a filesystem, or opening a device node is required.\nS:U - The use-after-free corrupts the host kernel's pmic_typec_pdphy and tcpm_port heap objects within the same OS security authority and does not cross a VM, IOMMU, or sandbox boundary.\nC:H - qcom_pmic_typec_pdphy_sig_reset_work() recovers the freed pmic_typec_pdphy via container_of and reads its lock, regmap, and tcpm_port; reclaiming that slab yields a classic UAF read/disclosure primitive.\nI:H - The dangling worker takes the freed lock, writes PD PHY registers through regmap, and calls tcpm_pd_hard_reset() on a possibly unregistered port, enabling heap corruption and control-flow hijack.\nA:H - Dereferencing the freed pmic_typec_pdphy from workqueue context, or queueing TCPM work on a destroyed port worker, causes a kernel oops or panic even without a full exploit, so availability impact is High."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/usb/typec/tcpm/qcom/qcom_pmic_typec_pdphy.c"], "versions": [{"version": "a4422ff221429c600c3dc5d0394fb3738b89d040", "lessThan": "0b69b166852dbf1f9532b22bd49f502e5970eb95", "status": "affected", "versionType": "git"}, {"version": "a4422ff221429c600c3dc5d0394fb3738b89d040", "lessThan": "b9a7eed472edbfa8dec0fdeafd5e796550a8a8b7", "status": "affected", "versionType": "git"}, {"version": "a4422ff221429c600c3dc5d0394fb3738b89d040", "lessThan": "d4e00a1eb39174e25ef759b8fb1111bba8e87b1e", "status": "affected", "versionType": "git"}, {"version": "a4422ff221429c600c3dc5d0394fb3738b89d040", "lessThan": "52d556f08547733948cc40b8b11e6b68dccee7b2", "status": "affected", "versionType": "git"}, {"version": "a4422ff221429c600c3dc5d0394fb3738b89d040", "lessThan": "7b0df6efd143f8085bdb68778a013a46f1349913", "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/usb/typec/tcpm/qcom/qcom_pmic_typec_pdphy.c"], "versions": [{"version": "6.5", "status": "affected"}, {"version": "0", "lessThan": "6.5", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.157", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.110", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.51", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2.5", "lessThanOrEqual": "7.2.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.3-rc2", "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": "6.5", "versionEndExcluding": "6.6.157"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.5", "versionEndExcluding": "6.12.110"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.5", "versionEndExcluding": "6.18.51"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.5", "versionEndExcluding": "7.2.5"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.5", "versionEndExcluding": "7.3-rc2"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/0b69b166852dbf1f9532b22bd49f502e5970eb95"}, {"url": "https://git.kernel.org/stable/c/b9a7eed472edbfa8dec0fdeafd5e796550a8a8b7"}, {"url": "https://git.kernel.org/stable/c/d4e00a1eb39174e25ef759b8fb1111bba8e87b1e"}, {"url": "https://git.kernel.org/stable/c/52d556f08547733948cc40b8b11e6b68dccee7b2"}, {"url": "https://git.kernel.org/stable/c/7b0df6efd143f8085bdb68778a013a46f1349913"}], "title": "usb: typec: qcom-pmic: cancel reset_work on stop", "x_generator": {"engine": "bippy-1.2.0"}}}}
