This brings the bloom map in line with\nmany other map types.\n\nThe lack of this protection can cause kernel crashes for value sizes\nthat overflow int's. Such a crash was caught by syzkaller. The next\npatch adds more guard-rails at a lower level."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["kernel/bpf/bloom_filter.c","tools/testing/selftests/bpf/prog_tests/bloom_filter_map.c"],"versions":[{"version":"9330986c03006ab1d33d243b7cfe598a7a3c1baa","lessThan":"fa6995eeb62e74b5a1480c73fb7b420c270784d3","status":"affected","versionType":"git"},{"version":"9330986c03006ab1d33d243b7cfe598a7a3c1baa","lessThan":"608e13706c8b6c658a0646f09ebced74ec367f7c","status":"affected","versionType":"git"},{"version":"9330986c03006ab1d33d243b7cfe598a7a3c1baa","lessThan":"c418afb9bf23e2f2b76cb819601e4a5d9dbab42d","status":"affected","versionType":"git"},{"version":"9330986c03006ab1d33d243b7cfe598a7a3c1baa","lessThan":"a8d89feba7e54e691ca7c4efc2a6264fa83f3687","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["kernel/bpf/bloom_filter.c","tools/testing/selftests/bpf/prog_tests/bloom_filter_map.c"],"versions":[{"version":"5.16","status":"affected"},{"version":"0","lessThan":"5.16","status":"unaffected","versionType":"semver"},{"version":"6.1.91","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.31","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.8.10","lessThanOrEqual":"6.8.*","status":"unaffected","versionType":"semver"},{"version":"6.9","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":"5.16","versionEndExcluding":"6.1.91"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"6.6.31"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"6.8.10"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"6.9"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/fa6995eeb62e74b5a1480c73fb7b420c270784d3"},{"url":"https://git.kernel.org/stable/c/608e13706c8b6c658a0646f09ebced74ec367f7c"},{"url":"https://git.kernel.org/stable/c/c418afb9bf23e2f2b76cb819601e4a5d9dbab42d"},{"url":"https://git.kernel.org/stable/c/a8d89feba7e54e691ca7c4efc2a6264fa83f3687"}],"title":"bpf: Check bloom filter map value size","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T03:43:50.111Z"},"title":"CVE Program Container","references":[{"url":"https://git.kernel.org/stable/c/fa6995eeb62e74b5a1480c73fb7b420c270784d3","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/608e13706c8b6c658a0646f09ebced74ec367f7c","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/c418afb9bf23e2f2b76cb819601e4a5d9dbab42d","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/a8d89feba7e54e691ca7c4efc2a6264fa83f3687","tags":["x_transferred"]}]},{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2024-36918","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-09-10T17:16:07.190878Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-09-11T17:35:00.289Z"}}]}}
