Make sure that it's taken by explicitly doing\nthat. Without it we got a splat:\n\n  WARNING: CPU: 0 PID: 10 at drivers/tty/serial/serial_core.c:3491 uart_handle_cts_change+0xa6/0xb0\n  ...\n  Workqueue: max3100-0 max3100_work [max3100]\n  RIP: 0010:uart_handle_cts_change+0xa6/0xb0\n  ...\n   max3100_handlerx+0xc5/0x110 [max3100]\n   max3100_work+0x12a/0x340 [max3100]","modified":"2026-04-16T04:39:45.563737148Z","published":"2024-06-21T10:18:23.573Z","related":["SUSE-SU-2024:2372-1","SUSE-SU-2024:2394-1","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-2024-38634.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/44b38924135d2093e2ec1812969464845dd66dc9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/77ab53371a2066fdf9b895246505f5ef5a4b5d47"},{"type":"WEB","url":"https://git.kernel.org/stable/c/78dbda51bb4241b88a52d71620f06231a341f9ba"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8296bb9e5925b6634259c5d4daee88f0cc0884ec"},{"type":"WEB","url":"https://git.kernel.org/stable/c/865b30c8661924ee9145f442bf32cea549faa869"},{"type":"WEB","url":"https://git.kernel.org/stable/c/93df2fba6c7dfa9a2f08546ea9a5ca4728758458"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cc121e3722a0a2c8f716ef991e5425b180a5fb94"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ea9b35372b58ac2931bfc1d5bc25e839d1221e30"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/06/msg00020.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/38xxx/CVE-2024-38634.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-38634"},{"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":"7831d56b0a3544cbb6f82f76c34ca95e24d5b676"},{"fixed":"44b38924135d2093e2ec1812969464845dd66dc9"},{"fixed":"ea9b35372b58ac2931bfc1d5bc25e839d1221e30"},{"fixed":"cc121e3722a0a2c8f716ef991e5425b180a5fb94"},{"fixed":"78dbda51bb4241b88a52d71620f06231a341f9ba"},{"fixed":"8296bb9e5925b6634259c5d4daee88f0cc0884ec"},{"fixed":"93df2fba6c7dfa9a2f08546ea9a5ca4728758458"},{"fixed":"865b30c8661924ee9145f442bf32cea549faa869"},{"fixed":"77ab53371a2066fdf9b895246505f5ef5a4b5d47"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-38634.json"}}],"schema_version":"1.7.5"}
