No race or uncontrollable condition is required.\nPR:L - The attacker needs control of an assigned VF but no PF or host administrative privilege or mailbox authentication. Delegated VF access is a low privilege in the originating tenant scope.\nUI:N - The PF processes the VF mailbox command automatically without any victim action.\nS:C - An untrusted VM or workload can control the VF while the malformed request corrupts the host PF kernel, crossing the tenant-to-host security boundary.\nC:H - The 16-bit ID reaches roughly 7.5 KiB beyond the bitmap into adjacent pointers and structures. The resulting corruption can enable host-kernel code execution and arbitrary memory disclosure.\nI:H - Invalid delete and add requests provide selected bit-set and bit-clear operations over adjacent kernel data, enabling pointer corruption and potentially host-kernel code execution.\nA:H - The repeatable out-of-bounds atomic memory operations can corrupt or fault kernel memory, directly causing a host kernel oops, panic, or hang."}]}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_main.c"],"versions":[{"version":"fe4144d47eef8453459c53a34e9d5940a3e6c219","lessThan":"46c7d9fe8dd869ea5de666aba8c1ec1061ca44a8","status":"affected","versionType":"git"},{"version":"fe4144d47eef8453459c53a34e9d5940a3e6c219","lessThan":"42c91dfa772c57de141e5a55a187ac760c0fd7e1","status":"affected","versionType":"git"},{"version":"fe4144d47eef8453459c53a34e9d5940a3e6c219","lessThan":"00e56a7706e10b3d00a258d81fcb85a7e96372d6","status":"affected","versionType":"git"},{"version":"fe4144d47eef8453459c53a34e9d5940a3e6c219","lessThan":"b7b4f3bf118f51b67691a55b464f04452e5dc6fc","status":"affected","versionType":"git"},{"version":"fe4144d47eef8453459c53a34e9d5940a3e6c219","lessThan":"95cca255a7a5ad782639ff0298c2a486707d1046","status":"affected","versionType":"git"},{"version":"fe4144d47eef8453459c53a34e9d5940a3e6c219","lessThan":"91a51d01be5c9f82c12c2921ca5cceaa31b67128","status":"affected","versionType":"git"},{"version":"fe4144d47eef8453459c53a34e9d5940a3e6c219","lessThan":"6ef935e65902bfed53980ad2754b06a284ea8ac1","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/ethernet/hisilicon/hns3/hns3pf/hclge_main.c"],"versions":[{"version":"5.3","status":"affected"},{"version":"0","lessThan":"5.3","status":"unaffected","versionType":"semver"},{"version":"5.10.248","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.198","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.160","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.120","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.64","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.3","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"6.19","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":"5.3","versionEndExcluding":"5.10.248"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.3","versionEndExcluding":"5.15.198"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.3","versionEndExcluding":"6.1.160"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.3","versionEndExcluding":"6.6.120"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.3","versionEndExcluding":"6.12.64"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.3","versionEndExcluding":"6.18.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.3","versionEndExcluding":"6.19"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/46c7d9fe8dd869ea5de666aba8c1ec1061ca44a8"},{"url":"https://git.kernel.org/stable/c/42c91dfa772c57de141e5a55a187ac760c0fd7e1"},{"url":"https://git.kernel.org/stable/c/00e56a7706e10b3d00a258d81fcb85a7e96372d6"},{"url":"https://git.kernel.org/stable/c/b7b4f3bf118f51b67691a55b464f04452e5dc6fc"},{"url":"https://git.kernel.org/stable/c/95cca255a7a5ad782639ff0298c2a486707d1046"},{"url":"https://git.kernel.org/stable/c/91a51d01be5c9f82c12c2921ca5cceaa31b67128"},{"url":"https://git.kernel.org/stable/c/6ef935e65902bfed53980ad2754b06a284ea8ac1"}],"title":"net:
