Once\ntls_decrypt_async_wait() returns, every AEAD operation\nhas completed and the engine no longer references those\nskbs, so they can be freed unconditionally.\n\nA subsequent patch adds batch async decryption to\ntls_sw_read_sock(), introducing a new call site that\nmust drain pending AEAD operations and release held\nskbs. Move __skb_queue_purge(&ctx->async_hold) into\ntls_decrypt_async_wait() so the purge is centralized\nand every caller -- recvmsg's drain path, the -EBUSY\nfallback in tls_do_decryption(), and the new read_sock\nbatch path -- releases held skbs on synchronization\nwithout each site managing the purge independently.\n\nThis fixes a leak when tls_strp_msg_hold() fails part-way through,\nafter having added some cloned skbs to the async_hold\nqueue. tls_decrypt_sg() will then call tls_decrypt_async_wait() to\nprocess all pending decrypts, and drop back to synchronous mode, but\ntls_sw_recvmsg() only flushes the async_hold queue when one record has\nbeen processed in \"fully-async\" mode, which may not be the case here.\n\n[pabeni@redhat.com: added leak comment]"}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH"}}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/tls/tls_sw.c"],"versions":[{"version":"9f83fd0c179e0f458e824e417f9d5ad53443f685","lessThan":"ac435be7c7613eb13a5a8ceb5182e10b50c9ce87","status":"affected","versionType":"git"},{"version":"c61d4368197d65c4809d9271f3b85325a600586a","lessThan":"2dcf324855c34e7f934ce978aa19b645a8f3ee71","status":"affected","versionType":"git"},{"version":"39dec4ea3daf77f684308576baf483b55ca7f160","lessThan":"6dc11e0bd0a5466bcc76d275c09e5537bd0597dd","status":"affected","versionType":"git"},{"version":"b8a6ff84abbcbbc445463de58704686011edc8e1","lessThan":"9f557c7eae127b44d2e863917dc986a4b6cb1269","status":"affected","versionType":"git"},{"version":"b8a6ff84abbcbbc445463de58704686011edc8e1","lessThan":"fd8037e1f18ca5336934d0e0e7e1a4fe097e749d","status":"affected","versionType":"git"},{"version":"b8a6ff84abbcbbc445463de58704686011edc8e1","lessThan":"84a8335d8300576f1b377ae24abca1d9f197807f","status":"affected","versionType":"git"},{"version":"4fc109d0ab196bd943b7451276690fb6bb48c2e0","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/tls/tls_sw.c"],"versions":[{"version":"6.18","status":"affected"},{"version":"0","lessThan":"6.18","status":"unaffected","versionType":"semver"},{"version":"6.1.168","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.131","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.80","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.21","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"6.19.11","lessThanOrEqual":"6.19.*","status":"unaffected","versionType":"semver"},{"version":"7.0","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.1.158","versionEndExcluding":"6.1.168"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.6.114","versionEndExcluding":"6.6.131"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.12.55","versionEndExcluding":"6.12.80"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.18","versionEndExcluding":"6.18.21"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.18","versionEndExcluding":"6.19.11"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.18","versionEndExcluding":"7.0"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.17.5"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/ac435be7c7613eb13a5a8ceb5182e10b50c9ce87"},{"url":"https://git.kernel.org/stable/c/2dcf324855c34e7f934ce978aa19b645a8f3ee71"},{"url":"https://git.kernel.org/stable/c/6dc11e0bd0a5466bcc76d275c09e5537bd0597dd"},{"url":"https://git.kernel.org/stable/c/9f557c7eae127b44d2e863917dc986a4b6cb1269"},{"url":"https://git.kernel.org/stable/c/fd8037e1f18ca5336934d0e0e7e1a4fe097e749d"},{"url":"https://git.kernel.org/stable/c/84a8335d8300576f1b377ae24abca1d9f197807f"}],"title":"tls: Purge async_hold in tls_decrypt_async_wait()","x_generator":{"engine":"bippy-1.2.0"}}}}
