{"id":"AZL-99525","summary":"CVE-2026-80904 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet/tls: Fail tls_sw_splice_read() after a failed async decrypt\n\nWhen an async decrypt fails, tls_decrypt_done() records the error in\nctx-\u003easync_wait.err and calls tls_err_abort(), which stores it in\nsk_err. tls_sw_recvmsg() and tls_sw_read_sock() each read\nasync_wait.err once they hold the reader lock and fail the call: a\nrecord that did not authenticate breaks the connection.\n\ntls_sw_splice_read() has no such check, and sk_err does not stand in\nfor one. tls_rx_rec_wait() tests sk_err only inside the loop it\nskips whenever a record is already parsed, and the first reader to\nreach sock_error() clears it, while async_wait.err persists. A\nsplice therefore keeps delivering records on a connection that\nrecvmsg() and read_sock() refuse to read.\n\nRead async_wait.err in tls_sw_splice_read() as the other two readers\ndo.","modified":"2026-09-05T14:16:57.890775690Z","published":"2026-09-04T18:17:59Z","upstream":["CVE-2026-80904"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80904"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-99525.json"}}],"schema_version":"1.9.0"}
