CVE-2025-37967 (GCVE-0-2025-37967)

Vulnerability from cvelistv5 – Published: 2025-05-20 16:47 – Updated: 2026-05-11 21:18

Title

usb: typec: ucsi: displayport: Fix deadlock

Summary

In the Linux kernel, the following vulnerability has been resolved: usb: typec: ucsi: displayport: Fix deadlock This patch introduces the ucsi_con_mutex_lock / ucsi_con_mutex_unlock functions to the UCSI driver. ucsi_con_mutex_lock ensures the connector mutex is only locked if a connection is established and the partner pointer is valid. This resolves a deadlock scenario where ucsi_displayport_remove_partner holds con->mutex waiting for dp_altmode_work to complete while dp_altmode_work attempts to acquire it.

Severity

5.5 (Medium)

Este parche incorpora las funciones ucsi_con_mutex_lock y ucsi_con_mutex_unlock al controlador UCSI. ucsi_con_mutex_lock garantiza que el mutex del conector solo se bloquee si se establece una conexi\u00f3n y el puntero del asociado es v\u00e1lido. Esto resuelve un escenario de interbloqueo donde ucsi_displayport_remove_partner mantiene con-\u0026gt;mutex esperando a que dp_altmode_work complete su ejecuci\u00f3n mientras dp_altmode_work intenta adquirirlo.\"}],\"affected\":[{\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"affectedData\":[{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"unaffected\",\"programFiles\":[\"drivers/usb/typec/ucsi/displayport.c\",\"drivers/usb/typec/ucsi/ucsi.c\",\"drivers/usb/typec/ucsi/ucsi.h\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"af8622f6a585d8d82b11cd7987e082861fd0edd3\",\"lessThan\":\"f4bd982563c2fd41ec9ca6c517c392d759db801c\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"af8622f6a585d8d82b11cd7987e082861fd0edd3\",\"lessThan\":\"f32451ca4cb7dc53f2a0e2e66b84d34162747eb7\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"af8622f6a585d8d82b11cd7987e082861fd0edd3\",\"lessThan\":\"962ce9028ca6eb450d5c205238a3ee27de9d214d\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"af8622f6a585d8d82b11cd7987e082861fd0edd3\",\"lessThan\":\"5924b324468845fc795bd76f588f51d7ab4f202d\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"af8622f6a585d8d82b11cd7987e082861fd0edd3\",\"lessThan\":\"61fc1a8e1e10cc784cab5829930838aaf1d37af5\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"af8622f6a585d8d82b11cd7987e082861fd0edd3\",\"lessThan\":\"364618c89d4c57c85e5fc51a2446cd939bf57802\",\"versionType\":\"git\",\"status\":\"affected\"}]},{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"affected\",\"programFiles\":[\"drivers/usb/typec/ucsi/displayport.c\",\"drivers/usb/typec/ucsi/ucsi.c\",\"drivers/usb/typec/ucsi/ucsi.h\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"5.2\",\"status\":\"affected\"},{\"version\":\"0\",\"lessThan\":\"5.2\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"5.15.184\",\"lessThanOrEqual\":\"5.15.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.1.140\",\"lessThanOrEqual\":\"6.1.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.6.92\",\"lessThanOrEqual\":\"6.6.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.12.30\",\"lessThanOrEqual\":\"6.12.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.14.7\",\"lessThanOrEqual\":\"6.14.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.15\",\"lessThanOrEqual\":\"*\",\"versionType\":\"original_commit_for_fix\",\"status\":\"unaffected\"}]}]}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H\",\"baseScore\":5.5,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":1.8,\"impactScore\":3.6}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-667\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.2\",\"versionEndExcluding\":\"5.15.184\",\"matchCriteriaId\":\"06266B56-FC7F-486B-A2C8-3F1336E6BCA3\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.16\",\"versionEndExcluding\":\"6.1.140\",\"matchCriteriaId\":\"EEA541CD-1863-4E7F-85F5-EAC305910323\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.2\",\"versionEndExcluding\":\"6.6.92\",\"matchCriteriaId\":\"7787FD66-D748-44AF-A052-DE495E1E23AE\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.7\",\"versionEndExcluding\":\"6.12.30\",\"matchCriteriaId\":\"8F43EF2E-9448-4BCA-99D9-DAEAEB7523C5\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.13\",\"versionEndExcluding\":\"6.14.7\",\"matchCriteriaId\":\"5715A6F5-A34A-4B27-8A64-82825E963995\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:6.15:rc1:*:*:*:*:*:*\",\"matchCriteriaId\":\"8D465631-2980-487A-8E65-40AE2B9F8ED1\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:6.15:rc2:*:*:*:*:*:*\",\"matchCriteriaId\":\"4C9D071F-B28E-46EC-AC61-22B913390211\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:6.15:rc3:*:*:*:*:*:*\",\"matchCriteriaId\":\"13FC0DDE-E513-465E-9E81-515702D49B74\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:6.15:rc4:*:*:*:*:*:*\",\"matchCriteriaId\":\"8C7B5B0E-4EEB-48F5-B4CF-0935A7633845\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:6.15:rc5:*:*:*:*:*:*\",\"matchCriteri

GHSA-W939-6X76-94VC

Vulnerability from github – Published: 2025-05-20 18:30 – Updated: 2025-12-16 21:30

Details

In the Linux kernel, the following vulnerability has been resolved:

usb: typec: ucsi: displayport: Fix deadlock

This patch introduces the ucsi_con_mutex_lock / ucsi_con_mutex_unlock functions to the UCSI driver. ucsi_con_mutex_lock ensures the connector mutex is only locked if a connection is established and the partner pointer is valid. This resolves a deadlock scenario where ucsi_displayport_remove_partner holds con->mutex waiting for dp_altmode_work to complete while dp_altmode_work attempts to acquire it.

Severity

5.5 (Medium)
