{"id":"CVE-2024-36887","summary":"e1000e: change usleep_range to udelay in PHY mdic access","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ne1000e: change usleep_range to udelay in PHY mdic access\n\nThis is a partial revert of commit 6dbdd4de0362 (\"e1000e: Workaround\nfor sporadic MDI error on Meteor Lake systems\"). The referenced commit\nused usleep_range inside the PHY access routines, which are sometimes\ncalled from an atomic context. This can lead to a kernel panic in some\nscenarios, such as cable disconnection and reconnection on vPro systems.\n\nSolve this by changing the usleep_range calls back to udelay.","modified":"2026-03-20T12:36:50.037543Z","published":"2024-05-30T15:28:55.630Z","related":["MGASA-2024-0263","MGASA-2024-0266","SUSE-SU-2024:2571-1","SUSE-SU-2024:2896-1","SUSE-SU-2024:2973-1","SUSE-SU-2025:20008-1","SUSE-SU-2025:20028-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/36xxx/CVE-2024-36887.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/387f295cb2150ed164905b648d76dfcbd3621778"},{"type":"WEB","url":"https://git.kernel.org/stable/c/950d5226cd6bb83ba720961a8d4d5cf79e6afd57"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f8a139656c95db893a543159873c57a470d7376d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/36xxx/CVE-2024-36887.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-36887"},{"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":"1d16cd91cd319d5bf6230c8493feb56a61e486a1"},{"fixed":"f8a139656c95db893a543159873c57a470d7376d"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0a4e3c2d976aa4dd38951afd6267f74ef3fade0e"},{"fixed":"950d5226cd6bb83ba720961a8d4d5cf79e6afd57"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6dbdd4de0362c37e54e8b049781402e5a409e7d0"},{"fixed":"387f295cb2150ed164905b648d76dfcbd3621778"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-36887.json"}}],"schema_version":"1.7.5"}
