This will loop over the\nmsg until msg_pl is full, checked by sk_msg_full(msg_pl). The user\ncan also set the MORE flag to hint stack to delay sending until receiving\nmore pages and ideally a full buffer.\n\nIf the user adds more pages to the msg than can fit in the msg_pl\nscatterlist (MAX_MSG_FRAGS) we should ignore the MORE flag and send\nthe buffer anyways.\n\nWhat actually happens though is we abort the msg to msg_pl scatterlist\nsetup and then because we forget to set 'full record' indicating we\ncan no longer consume data without a send we fallthrough to the 'continue'\npath which will check if msg_data_left(msg) has more bytes to send and\nthen attempts to fit them in the already full msg_pl. Then next\niteration of sender doing send will encounter a full msg_pl and throw\nthe warning in the syzbot report.\n\nTo fix simply check if we have a full_record in splice code path and\nif not send the msg regardless of MORE flag."}],"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":"fe1e81d4f73b6cbaed4fcc476960d26770642842","lessThan":"02e368eb1444a4af649b73cbe2edd51780511d86","status":"affected","versionType":"git"},{"version":"fe1e81d4f73b6cbaed4fcc476960d26770642842","lessThan":"294e7ea85f34748f04e5f3f9dba6f6b911d31aa8","status":"affected","versionType":"git"},{"version":"fe1e81d4f73b6cbaed4fcc476960d26770642842","lessThan":"dc9dfc8dc629e42f2234e3327b75324ffc752bc9","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":"6.5","status":"affected"},{"version":"0","lessThan":"6.5","status":"unaffected","versionType":"semver"},{"version":"6.6.14","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.7.2","lessThanOrEqual":"6.7.*","status":"unaffected","versionType":"semver"},{"version":"6.8","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":"6.5","versionEndExcluding":"6.6.14"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.5","versionEndExcluding":"6.7.2"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.5","versionEndExcluding":"6.8"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/02e368eb1444a4af649b73cbe2edd51780511d86"},{"url":"https://git.kernel.org/stable/c/294e7ea85f34748f04e5f3f9dba6f6b911d31aa8"},{"url":"https://git.kernel.org/stable/c/dc9dfc8dc629e42f2234e3327b75324ffc752bc9"}],"title":"net: tls, fix WARNIING in __sk_msg_free","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T03:21:48.073Z"},"title":"CVE Program Container","references":[{"url":"https://git.kernel.org/stable/c/02e368eb1444a4af649b73cbe2edd51780511d86","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/294e7ea85f34748f04e5f3f9dba6f6b911d31aa8","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/dc9dfc8dc629e42f2234e3327b75324ffc752bc9","tags":["x_transferred"]}]},{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2024-35841","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-09-10T15:41:46.618855Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-09-11T17:33:18.283Z"}}]}}
