This is a problem, however, as there's a gap\nbetween the two phases in which a packet may come into rxrpc_encap_rcv()\nfrom the UDP packet but we oops when trying to wake the not-yet created I/O\nthread.\n\nAs a quick fix, just make rxrpc_encap_rcv() discard the packet if there's\nno I/O thread yet.\n\nA better, but more intrusive fix would perhaps be to rearrange things such\nthat the socket creation is done by the I/O thread."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/rxrpc/ar-internal.h","net/rxrpc/io_thread.c","net/rxrpc/local_object.c"],"versions":[{"version":"a275da62e8c111b897b9cb73eb91df2f4e475ca5","lessThan":"cdf4bbbdb956d7426f687f38757ebca2a2759a0f","status":"affected","versionType":"git"},{"version":"a275da62e8c111b897b9cb73eb91df2f4e475ca5","lessThan":"56e415202b8a17de6496f4023e545fcb66f118ec","status":"affected","versionType":"git"},{"version":"a275da62e8c111b897b9cb73eb91df2f4e475ca5","lessThan":"c64f5fc95e9612fdf75587c8e21e494e614c18e2","status":"affected","versionType":"git"},{"version":"a275da62e8c111b897b9cb73eb91df2f4e475ca5","lessThan":"bc212465326e8587325f520a052346f0b57360e6","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/rxrpc/ar-internal.h","net/rxrpc/io_thread.c","net/rxrpc/local_object.c"],"versions":[{"version":"6.2","status":"affected"},{"version":"0","lessThan":"6.2","status":"unaffected","versionType":"semver"},{"version":"6.6.55","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.10.14","lessThanOrEqual":"6.10.*","status":"unaffected","versionType":"semver"},{"version":"6.11.3","lessThanOrEqual":"6.11.*","status":"unaffected","versionType":"semver"},{"version":"6.12","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":"6.2","versionEndExcluding":"6.6.55"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"6.10.14"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"6.11.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"6.12"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/cdf4bbbdb956d7426f687f38757ebca2a2759a0f"},{"url":"https://git.kernel.org/stable/c/56e415202b8a17de6496f4023e545fcb66f118ec"},{"url":"https://git.kernel.org/stable/c/c64f5fc95e9612fdf75587c8e21e494e614c18e2"},{"url":"https://git.kernel.org/stable/c/bc212465326e8587325f520a052346f0b57360e6"}],"title":"rxrpc: Fix a race between socket set up and I/O thread creation","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2024-49864","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-10-22T13:47:53.708864Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-10-22T13:48:52.920Z"}}]}}
