{"id":"CVE-2024-41007","summary":"tcp: avoid too many retransmit packets","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ntcp: avoid too many retransmit packets\n\nIf a TCP socket is using TCP_USER_TIMEOUT, and the other peer\nretracted its window to zero, tcp_retransmit_timer() can\nretransmit a packet every two jiffies (2 ms for HZ=1000),\nfor about 4 minutes after TCP_USER_TIMEOUT has 'expired'.\n\nThe fix is to make sure tcp_rtx_probe0_timed_out() takes\nicsk-\u003eicsk_user_timeout into account.\n\nBefore blamed commit, the socket would not timeout after\nicsk-\u003eicsk_user_timeout, but would use standard exponential\nbackoff for the retransmits.\n\nAlso worth noting that before commit e89688e3e978 (\"net: tcp:\nfix unexcepted socket die when snd_wnd is 0\"), the issue\nwould last 2 minutes instead of 4.","modified":"2026-04-02T12:17:24.309029Z","published":"2024-07-15T08:48:10.174Z","related":["ALSA-2024:7000","ALSA-2024:7001","SUSE-SU-2024:3190-1","SUSE-SU-2024:3194-1","SUSE-SU-2024:3195-1","SUSE-SU-2024:3209-1","SUSE-SU-2024:3383-1","SUSE-SU-2024:3483-1","SUSE-SU-2025:20044-1","SUSE-SU-2025:20047-1","SUSE-SU-2026:0473-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/41xxx/CVE-2024-41007.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/04317a2471c2f637b4c49cbd0e9c0d04a519f570"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5d7e64d70a11d988553a08239c810a658e841982"},{"type":"WEB","url":"https://git.kernel.org/stable/c/66cb64a1d2239cd0309f9b5038b05462570a5be1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7bb7670f92bfbd05fc41a8f9a8f358b7ffed65f4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/97a9063518f198ec0adb2ecb89789de342bb8283"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d2346fca5bed130dc712f276ac63450201d52969"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dfcdd7f89e401d2c6616be90c76c2fac3fa98fde"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e113cddefa27bbf5a79f72387b8fbd432a61a466"},{"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/2024/41xxx/CVE-2024-41007.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-41007"},{"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":"b701a99e431db784714c32fc6b68123045714679"},{"fixed":"7bb7670f92bfbd05fc41a8f9a8f358b7ffed65f4"},{"fixed":"d2346fca5bed130dc712f276ac63450201d52969"},{"fixed":"5d7e64d70a11d988553a08239c810a658e841982"},{"fixed":"04317a2471c2f637b4c49cbd0e9c0d04a519f570"},{"fixed":"e113cddefa27bbf5a79f72387b8fbd432a61a466"},{"fixed":"dfcdd7f89e401d2c6616be90c76c2fac3fa98fde"},{"fixed":"66cb64a1d2239cd0309f9b5038b05462570a5be1"},{"fixed":"97a9063518f198ec0adb2ecb89789de342bb8283"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-41007.json"}}],"schema_version":"1.7.5"}
