{"id":"CVE-2026-23132","summary":"drm/bridge: synopsys: dw-dp: fix error paths of dw_dp_bind","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/bridge: synopsys: dw-dp: fix error paths of dw_dp_bind\n\nFix several issues in dw_dp_bind() error handling:\n\n1. Missing return after drm_bridge_attach() failure - the function\n   continued execution instead of returning an error.\n\n2. Resource leak: drm_dp_aux_register() is not a devm function, so\n   drm_dp_aux_unregister() must be called on all error paths after\n   aux registration succeeds. This affects errors from:\n   - drm_bridge_attach()\n   - phy_init()\n   - devm_add_action_or_reset()\n   - platform_get_irq()\n   - devm_request_threaded_irq()\n\n3. Bug fix: platform_get_irq() returns the IRQ number or a negative\n   error code, but the error path was returning ERR_PTR(ret) instead\n   of ERR_PTR(dp-\u003eirq).\n\nUse a goto label for cleanup to ensure consistent error handling.","modified":"2026-08-12T03:51:32.996568828Z","published":"2026-02-14T15:14:32.334Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23132.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1a0f69e3c28477b97d3609569b7e8feb4b6162e8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/569ed6a73e927a34cae4ae6de1464c0737a5ec44"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23132.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23132"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"86eecc3a9c2e06462f6a273fcd24150b6da787de"},{"fixed":"569ed6a73e927a34cae4ae6de1464c0737a5ec44"},{"fixed":"1a0f69e3c28477b97d3609569b7e8feb4b6162e8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-23132.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.18.0"},{"fixed":"6.18.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-23132.json"}}],"schema_version":"1.9.0"}
