However, the IRQ domains set\nup earlier by mtk_pcie_init_irq_domain() are never freed.\n\nFix this by refactoring mtk_pcie_irq_teardown() into a per-port helper,\nmtk_pcie_irq_teardown_port(), and calling it from mtk_pcie_setup() when\nmtk_pcie_enable_port() fails. Since the IRQ teardown must only happen in\nthe probe error path (during resume, child devices may have active MSI\nmappings and the NOIRQ context prohibits sleeping locks),\nmtk_pcie_enable_port() is changed to return an error code so callers can\ndistinguish the two paths and act accordingly.\n\nThis issue was reported by Sashiko while reviewing the EcoNet EN7528 SoC\nsupport series.","epss":{"date":"2026-11-10","percentile":0.0811,"score":0.00184},"exploits":[],"kev":null,"metrics":[{"score":5.5,"severity":"medium","source":"NVD: nvd@nist.gov","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1794506771250,"publishedAt":1784969488309,"references":[{"source":"CNA: Linux","tags":[],"url":"https://git.kernel.org/stable/c/e23da72ef202654a7d5269885c4fa39a8404db76"},{"source":"CNA: Linux","tags":[],"url":"https://git.kernel.org/stable/c/ec7c05eed47d8b15c45380aee7ca168a82e15035"},{"source":"CNA: Linux","tags":[],"url":"https://git.kernel.org/stable/c/1fbe8972a39548a633d06d7b03a01b7b119a2c12"},{"source":"CNA: Linux","tags":[],"url":"https://git.kernel.org/stable/c/fe8c701a53c2816cd82301f66c671d952003c1b0"},{"source":"CNA: Linux","tags":[],"url":"https://git.kernel.org/stable/c/ce52e494a7555bdae1d990a2654fd7547ef6d986"},{"source":"CNA: Linux","tags":[],"url":"https://git.kernel.org/stable/c/6e6a529d6f779413379b4404c9ef6a36c0337225"},{"source":"CNA: Linux","tags":[],"url":"https://git.kernel.org/stable/c/df77314b3bedbd9ad5d6f0682f98b99e3c5f7e2e"},{"source":"CNA: Linux","tags":[],"url":"https://git.kernel.org/stable/c/f865a57896bd92d7662eb2818d8f48872e2cbbc7"},{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"],"url":"https://git.kernel.org/stable/c/1fbe8972a39548a633d06d7b03a01b7b119a2c12"},{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"],"url":"https://git.kernel.org/stable/c/6e6a529d6f779413379b4404c9ef6a36c0337225"},{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"],"url":"https://git.kernel.org/stable/c/ce52e494a7555bdae1d990a2654fd7547ef6d986"},{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"],"url":"https://git.kernel.org/stable/c/df77314b3bedbd9ad5d6f0682f98b99e3c5f7e2e"},{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"],"url":"https://git.kernel.org/stable/c/e23da72ef202654a7d5269885c4fa39a8404db76"},{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"],"url":"https://git.kernel.org/stable/c/ec7c05eed47d8b15c45380aee7ca168a82e15035"},{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"],"url":"https://git.kernel.org/stable/c/f865a57896bd92d7662eb2818d8f48872e2cbbc7"},{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"],"url":"https://git.kernel.org/stable/c/fe8c701a53c2816cd82301f66c671d952003c1b0"}],"remediation":[{"kind":"fix","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","text":"The reporting source identifies this reference as a patch.
