The net\ncore therefore leaves dev->tstats NULL for PFCP devices.\n\nCreating a PFCP rtnetlink device can immediately ask the new netdev for\nstats while building the RTM_NEWLINK notification.  That reaches\ndev_get_tstats64() and dereferences the NULL dev->tstats pointer.\n\nSet pcpu_stat_type to NETDEV_PCPU_STAT_TSTATS during PFCP link setup so\nthe net core allocates the storage expected by dev_get_tstats64()."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/pfcp.c"],"versions":[{"version":"76c8764ef36a5d37ea2e551bda28ac7f028383ba","lessThan":"56b4ad500fd1282ef04db3c4beae5b54ab093a53","status":"affected","versionType":"git"},{"version":"76c8764ef36a5d37ea2e551bda28ac7f028383ba","lessThan":"51a1d9836acc76a1bd16170b2f4b35f11036593f","status":"affected","versionType":"git"},{"version":"76c8764ef36a5d37ea2e551bda28ac7f028383ba","lessThan":"67e4b283de36d9eebf95acdea5d6674b6ef4b2f4","status":"affected","versionType":"git"},{"version":"76c8764ef36a5d37ea2e551bda28ac7f028383ba","lessThan":"24041543da8cd84eb5d8ae738c534372fff54820","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/pfcp.c"],"versions":[{"version":"6.10","status":"affected"},{"version":"0","lessThan":"6.10","status":"unaffected","versionType":"semver"},{"version":"6.12.97","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.40","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.1.5","lessThanOrEqual":"7.1.*","status":"unaffected","versionType":"semver"},{"version":"7.2","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":"6.10","versionEndExcluding":"6.12.97"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.10","versionEndExcluding":"6.18.40"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.10","versionEndExcluding":"7.1.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.10","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/56b4ad500fd1282ef04db3c4beae5b54ab093a53"},{"url":"https://git.kernel.org/stable/c/51a1d9836acc76a1bd16170b2f4b35f11036593f"},{"url":"https://git.kernel.org/stable/c/67e4b283de36d9eebf95acdea5d6674b6ef4b2f4"},{"url":"https://git.kernel.org/stable/c/24041543da8cd84eb5d8ae738c534372fff54820"}],"title":"net: pfcp: allocate per-cpu tstats for PFCP netdevs","x_generator":{"engine":"bippy-1.2.0"}}}}
