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"}}}}
