{"id":"CVE-2025-38094","summary":"net: cadence: macb: Fix a possible deadlock in macb_halt_tx.","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: cadence: macb: Fix a possible deadlock in macb_halt_tx.\n\nThere is a situation where after THALT is set high, TGO stays high as\nwell. Because jiffies are never updated, as we are in a context with\ninterrupts disabled, we never exit that loop and have a deadlock.\n\nThat deadlock was noticed on a sama5d4 device that stayed locked for days.\n\nUse retries instead of jiffies so that the timeout really works and we do\nnot have a deadlock anymore.","modified":"2026-03-20T12:42:43.265778Z","published":"2025-07-03T07:44:17.442Z","related":["SUSE-SU-2025:02846-1","SUSE-SU-2025:02853-1","SUSE-SU-2025:02923-1","SUSE-SU-2025:02969-1","SUSE-SU-2025:02996-1","SUSE-SU-2025:02997-1","SUSE-SU-2025:03011-1","SUSE-SU-2025:03023-1","SUSE-SU-2025:20577-1","SUSE-SU-2025:20586-1","SUSE-SU-2025:20601-1","SUSE-SU-2025:20602-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38094.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0772a608d799ac0d127c0a36047a2725777aba9d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1d60c0781c1bbeaa1196b0d8aad5c435f06cb7c4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3e64d35475aa21d13dab71da51de51923c1a3a48"},{"type":"WEB","url":"https://git.kernel.org/stable/c/64675a9c00443b2e8af42af08c38fc1b78b68ba2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/84f98955a9de0e0f591df85aa1a44f3ebcf1cb37"},{"type":"WEB","url":"https://git.kernel.org/stable/c/aace6b63892ce8307e502a60fe2f5a4bc6e1cfe7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c92d6089d8ad7d4d815ebcedee3f3907b539ff1f"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/08/msg00010.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/10/msg00007.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38094.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38094"},{"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":"e86cd53afc5907f7c221b709916e2dd354e14691"},{"fixed":"0772a608d799ac0d127c0a36047a2725777aba9d"},{"fixed":"64675a9c00443b2e8af42af08c38fc1b78b68ba2"},{"fixed":"aace6b63892ce8307e502a60fe2f5a4bc6e1cfe7"},{"fixed":"1d60c0781c1bbeaa1196b0d8aad5c435f06cb7c4"},{"fixed":"3e64d35475aa21d13dab71da51de51923c1a3a48"},{"fixed":"84f98955a9de0e0f591df85aa1a44f3ebcf1cb37"},{"fixed":"c92d6089d8ad7d4d815ebcedee3f3907b539ff1f"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-38094.json"}}],"schema_version":"1.7.5"}
