It will ensure the attribute being described produces\na valid nlattr pointer in info->attrs before entering into each handler\nin vdpa_nl_ops.\n\nThat is to say, the missing part in vdpa_nl_policy may lead to illegal\nnlattr after parsing, which could lead to OOB read just like CVE-2023-3773.\n\nThis patch adds the missing nla_policy for vdpa features attr to avoid\nsuch bugs."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/vdpa/vdpa.c"],"versions":[{"version":"90fea5a800c3dd80fb8ad9a02929bcef5fde42b8","lessThan":"44b508cc96889e61799cc0fc6c00766a54f3ab5a","status":"affected","versionType":"git"},{"version":"90fea5a800c3dd80fb8ad9a02929bcef5fde42b8","lessThan":"645d17e06c502e71b880b2b854930e5a64014640","status":"affected","versionType":"git"},{"version":"90fea5a800c3dd80fb8ad9a02929bcef5fde42b8","lessThan":"79c8651587504ba263d2fd67fd4406240fb21f69","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/vdpa/vdpa.c"],"versions":[{"version":"6.1","status":"affected"},{"version":"0","lessThan":"6.1","status":"unaffected","versionType":"semver"},{"version":"6.1.47","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.4.12","lessThanOrEqual":"6.4.*","status":"unaffected","versionType":"semver"},{"version":"6.5","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","versionEndExcluding":"6.1.47"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.1","versionEndExcluding":"6.4.12"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.1","versionEndExcluding":"6.5"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/44b508cc96889e61799cc0fc6c00766a54f3ab5a"},{"url":"https://git.kernel.org/stable/c/645d17e06c502e71b880b2b854930e5a64014640"},{"url":"https://git.kernel.org/stable/c/79c8651587504ba263d2fd67fd4406240fb21f69"}],"title":"vdpa: Add features attr to vdpa_nl_policy for nlattr length check","x_generator":{"engine":"bippy-1.2.0"}}}}
