{"id":"CVE-2024-40967","summary":"serial: imx: Introduce timeout when waiting on transmitter empty","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nserial: imx: Introduce timeout when waiting on transmitter empty\n\nBy waiting at most 1 second for USR2_TXDC to be set, we avoid a potential\ndeadlock.\n\nIn case of the timeout, there is not much we can do, so we simply ignore\nthe transmitter state and optimistically try to continue.","modified":"2026-08-12T03:51:19.563525883Z","published":"2024-07-12T12:32:06.816Z","related":["SUSE-SU-2024:2892-1","SUSE-SU-2024:2894-1","SUSE-SU-2024:2901-1","SUSE-SU-2024:2939-1","SUSE-SU-2024:2940-1","SUSE-SU-2024:2947-1","SUSE-SU-2024:3194-1","SUSE-SU-2024:3195-1","SUSE-SU-2024:3383-1","SUSE-SU-2025:20044-1","SUSE-SU-2025:20047-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/40xxx/CVE-2024-40967.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/53b2c95547427c358f45515a9f144efee95e3701"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7f2b9ab6d0b26f16cd38dd9fd91d51899635f7c7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7f9e70c68b7ace0141fe3bc94bf7b61296b71916"},{"type":"WEB","url":"https://git.kernel.org/stable/c/982ae3376c4c91590d38dc8a676c10f7df048a44"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e533e4c62e9993e62e947ae9bbec34e4c7ae81c2"},{"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/2024/40xxx/CVE-2024-40967.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-40967"},{"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":"9ec1882df244c4ee1baa692676fef5e8b0f5487d"},{"fixed":"7f2b9ab6d0b26f16cd38dd9fd91d51899635f7c7"},{"fixed":"7f9e70c68b7ace0141fe3bc94bf7b61296b71916"},{"fixed":"982ae3376c4c91590d38dc8a676c10f7df048a44"},{"fixed":"53b2c95547427c358f45515a9f144efee95e3701"},{"fixed":"e533e4c62e9993e62e947ae9bbec34e4c7ae81c2"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0"},{"last_affected":"c096552004244868391b29f319ea8889d55abe19"},{"last_affected":"86236252d2449313bdbac790023cbc957bf6e426"},{"last_affected":"34d4dda865d8174f4a437f313c457c42a8fa9535"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"3.2.30"},{"fixed":"3.3"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"3.4.12"},{"fixed":"3.5"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"3.5.5"},{"fixed":"3.6"}]}],"versions":["v3.5-rc3","v3.5.4","v3.4.11","v3.5","v3.2.29","v3.4.10","v3.5.3","v3.2.28","v3.4-rc4","v3.4.9","v3.5.2","v3.2.27","v3.4.8","v3.5.1","v3.2.26","v3.4.7","v3.2.25","v3.2.24","v3.4.6","v3.5-rc7","v3.2.23","v3.5-rc5","v3.5-rc6","v3.4.5","v3.4.4","v3.5-rc2","v3.2.22","v3.5-rc1","v3.5-rc4","v3.2.21","v3.4","v3.4.3","v3.2.20","v3.4.2","v3.2.19","v3.4.1","v3.2.18","v3.4-rc2","v3.4-rc1","v3.2.17","v3.4-rc7","v3.4-rc6","v3.4-rc3","v3.4-rc5","v3.2.16","v3.2.15","v3.3","v3.2.14","v3.2.13","v3.3-rc6","v3.3-rc3","v3.2.12","v3.3-rc7","v3.2.11","v3.3-rc2","v3.3-rc5","v3.2","v3.2.10","v3.3-rc4","v3.2.9","v3.3-rc1","v3.2.8","v3.2.7","v3.2.6","v3.2.5","v3.2.4","v3.2.3","v3.2.2","v3.2.1","v3.2-rc4","v3.2-rc7","v3.2-rc6","v3.2-rc5","v3.2-rc3","v3.1","v3.2-rc2","v3.2-rc1","v3.1-rc1","v3.1-rc9","v3.1-rc8","v3.1-rc10","v3.1-rc7","v3.1-rc3","v3.1-rc2","v3.1-rc4","v3.1-rc5","v3.0","v3.1-rc6","v3.0-rc7","v3.0-rc4","v3.0-rc6","v3.0-rc5","v3.0-rc3","v3.0-rc1","v2.6.39","v3.0-rc2","v2.6.38","v2.6.39-rc2","v2.6.39-rc7","v2.6.39-rc5","v2.6.39-rc1","v2.6.38-rc7","v2.6.39-rc6","v2.6.39-rc4","v2.6.39-rc3","v2.6.37","v2.6.38-rc1","v2.6.38-rc8","v2.6.38-rc2","v2.6.38-rc6","v2.6.38-rc5","v2.6.38-rc4","v2.6.38-rc3","v2.6.37-rc4","v2.6.37-rc2","v2.6.36","v2.6.37-rc5","v2.6.37-rc8","v2.6.37-rc7","v2.6.37-rc6","v2.6.37-rc1","v2.6.37-rc3","v2.6.36-rc6","v2.6.35-rc4","v2.6.36-rc8","v2.6.35","v2.6.36-rc7","v2.6.36-rc3","v2.6.36-rc5","v2.6.36-rc4","v2.6.36-rc2","v2.6.36-rc1","v2.6.35-rc5","v2.6.35-rc6","v2.6.34","v2.6.35-rc3","v2.6.35-rc1","v2.6.35-rc2","v2.6.34-rc7","v2.6.34-rc6","v2.6.34-rc5","v2.6.34-rc4","v2.6.34-rc3","v2.6.34-rc2","v2.6.34-rc1","v2.6.33","v2.6.33-rc6","v2.6.33-rc8","v2.6.33-rc4","v2.6.33-rc5","v2.6.33-rc3","v2.6.33-rc7","v2.6.33-rc2","v2.6.32","v2.6.33-rc1","v2.6.32-rc8","v2.6.32-rc7","v2.6.32-rc6","v2.6.31","v2.6.32-rc5","v2.6.32-rc4","v2.6.32-rc2","v2.6.32-rc1","v2.6.32-rc3","v2.6.31-rc9","v2.6.31-rc1","v2.6.31-rc7","v2.6.31-rc8","v2.6.31-rc6","v2.6.30-rc6","v2.6.30","v2.6.31-rc4","v2.6.31-rc5","v2.6.31-rc3","v2.6.31-rc2","v2.6.30-rc7","v2.6.30-rc8","v2.6.30-rc5","v2.6.30-rc3","v2.6.30-rc4","v2.6.30-rc1","v2.6.30-rc2","v2.6.29","v2.6.29-rc8","v2.6.29-rc7","v2.6.29-rc5","v2.6.29-rc1","v2.6.29-rc6","v2.6.29-rc4","v2.6.29-rc3","v2.6.29-rc2","v2.6.28","v2.6.28-rc7","v2.6.28-rc9","v2.6.28-rc8","v2.6.28-rc6","v2.6.28-rc5","v2.6.28-rc4","v2.6.28-rc2","v2.6.28-rc3","v2.6.28-rc1","v2.6.27","v2.6.27-rc7","v2.6.27-rc9","v2.6.27-rc8","v2.6
