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 queue index 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":"13b00b135665c92065a27c0c39dd97e0f380bd4f","lessThan":"8ad9bc25cbdcec72e7ca43dd8281decb69ea9a70","status":"affected","versionType":"git"},{"version":"13b00b135665c92065a27c0c39dd97e0f380bd4f","lessThan":"ccb533b7070aeeb65c66ea5d590e9c62421dcd61","status":"affected","versionType":"git"},{"version":"13b00b135665c92065a27c0c39dd97e0f380bd4f","lessThan":"b3003e1b54e057f5f3124e437b80c3bef26ed3fe","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":"5.19","status":"affected"},{"version":"0","lessThan":"5.19","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":"5.19","versionEndExcluding":"6.1.47"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"6.4.12"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"6.5"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/8ad9bc25cbdcec72e7ca43dd8281decb69ea9a70"},{"url":"https://git.kernel.org/stable/c/ccb533b7070aeeb65c66ea5d590e9c62421dcd61"},{"url":"https://git.kernel.org/stable/c/b3003e1b54e057f5f3124e437b80c3bef26ed3fe"}],"title":"vdpa: Add queue index attr to vdpa_nl_policy for nlattr length check","x_generator":{"engine":"bippy-1.2.0"}}}}
