{"id":"CVE-2023-54306","summary":"net: tls: avoid hanging tasks on the tx_lock","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: tls: avoid hanging tasks on the tx_lock\n\nsyzbot sent a hung task report and Eric explains that adversarial\nreceiver may keep RWIN at 0 for a long time, so we are not guaranteed\nto make forward progress. Thread which took tx_lock and went to sleep\nmay not release tx_lock for hours. Use interruptible sleep where\npossible and reschedule the work if it can't take the lock.\n\nTesting: existing selftest passes","modified":"2026-04-02T09:46:50.289440Z","published":"2025-12-30T12:23:39.833Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/54xxx/CVE-2023-54306.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1f800f6aae57d2d8f63d32fff383017cbc11cf65"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7123a4337bf73132bbfb5437e4dc83ba864a9a1e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bde541a57b4204d0a800afbbd3d1c06c9cdb133f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/be5d5d0637fd88c18ee76024bdb22649a1de00d6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ccf1ccdc5926907befbe880b562b2a4b5f44c087"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f3221361dc85d4de22586ce8441ec2c67b454f5d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/54xxx/CVE-2023-54306.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-54306"},{"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":"79ffe6087e9145d2377385cac48d0d6a6b4225a5"},{"fixed":"bde541a57b4204d0a800afbbd3d1c06c9cdb133f"},{"fixed":"7123a4337bf73132bbfb5437e4dc83ba864a9a1e"},{"fixed":"be5d5d0637fd88c18ee76024bdb22649a1de00d6"},{"fixed":"1f800f6aae57d2d8f63d32fff383017cbc11cf65"},{"fixed":"ccf1ccdc5926907befbe880b562b2a4b5f44c087"},{"fixed":"f3221361dc85d4de22586ce8441ec2c67b454f5d"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0"},{"last_affected":"c8d6817345f4ba228d07380e571676405e112872"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-54306.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.4.0"},{"fixed":"5.4.235"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.5.0"},{"fixed":"5.10.173"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.100"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.18"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.2.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-54306.json"}}],"schema_version":"1.7.5"}
