{"id":"CVE-2024-38553","summary":"net: fec: remove .ndo_poll_controller to avoid deadlocks","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: fec: remove .ndo_poll_controller to avoid deadlocks\n\nThere is a deadlock issue found in sungem driver, please refer to the\ncommit ac0a230f719b (\"eth: sungem: remove .ndo_poll_controller to avoid\ndeadlocks\"). The root cause of the issue is that netpoll is in atomic\ncontext and disable_irq() is called by .ndo_poll_controller interface\nof sungem driver, however, disable_irq() might sleep. After analyzing\nthe implementation of fec_poll_controller(), the fec driver should have\nthe same issue. Due to the fec driver uses NAPI for TX completions, the\n.ndo_poll_controller is unnecessary to be implemented in the fec driver,\nso fec_poll_controller() can be safely removed.","modified":"2026-03-20T12:37:06.037027Z","published":"2024-06-19T13:35:24.743Z","related":["MGASA-2024-0263","MGASA-2024-0266","SUSE-SU-2024:2360-1","SUSE-SU-2024:2372-1","SUSE-SU-2024:2381-1","SUSE-SU-2024:2394-1","SUSE-SU-2024:2561-1","SUSE-SU-2024:2571-1","SUSE-SU-2024:2896-1","SUSE-SU-2024:2939-1","SUSE-SU-2024:2973-1","SUSE-SU-2025:20008-1","SUSE-SU-2025:20028-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/38xxx/CVE-2024-38553.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/87bcbc9b7e0b43a69d44efa5f32f11e32d08fa6f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/accdd6b912c4219b8e056d1f1ad2e85bc66ee243"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c2e0c58b25a0a0c37ec643255558c5af4450c9f5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d38625f71950e79e254515c5fc585552dad4b33e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e2348d8c61d03feece1de4c05f72e6e99f74c650"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/38xxx/CVE-2024-38553.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-38553"},{"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":"7f5c6addcdc039c1a7c435857e6284ecac5d97c8"},{"fixed":"e2348d8c61d03feece1de4c05f72e6e99f74c650"},{"fixed":"d38625f71950e79e254515c5fc585552dad4b33e"},{"fixed":"accdd6b912c4219b8e056d1f1ad2e85bc66ee243"},{"fixed":"87bcbc9b7e0b43a69d44efa5f32f11e32d08fa6f"},{"fixed":"c2e0c58b25a0a0c37ec643255558c5af4450c9f5"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-38553.json"}}],"schema_version":"1.7.5"}
