Callers need to\ntake care to handle these errors to avoid returning decrypted (shared)\nmemory to the page allocator, which could lead to functional or security\nissues.\n\nThe netvsc driver could free decrypted/shared pages if\nset_memory_decrypted() fails. Check the decrypted field in the gpadl\nto decide whether to free the memory.","state":0,"publishedAt":"2024-05-30T15:29:09.475+00:00","modifiedAt":"2026-10-30T12:18:27.153+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/net/hyperv/netvsc.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"d4dccf353db80e209f262e3973c834e6e48ba9a9\",\n                            \"lessThan\": \"fb671512ffb26570c05ba3fbe20752e645809192\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"d4dccf353db80e209f262e3973c834e6e48ba9a9\",\n                            \"lessThan\": \"a56fe611326332bf6b7126e5559590c57dcebad4\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"d4dccf353db80e209f262e3973c834e6e48ba9a9\",\n                            \"lessThan\": \"4aaed9dbe8acd2b6114458f0498a617283d6275b\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"d4dccf353db80e209f262e3973c834e6e48ba9a9\",\n                            \"lessThan\": \"bbf9ac34677b57506a13682b31a2a718934c0e31\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/net/hyperv/netvsc.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"5.16\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"5.16\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.1.191\",\n                            \"lessThanOrEqual\": \"6.1.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.6.31\",\n                            \"lessThanOrEqual\": \"6.6.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.8.10\",\n                            \"lessThanOrEqual\": \"6.8.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.9\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://git.kernel.org/stable/c/fb671512ffb26570c05ba3fbe20752e645809192","https://git.kernel.org/stable/c/a56fe611326332bf6b7126e5559590c57dcebad4","https://git.kernel.org/stable/c/4aaed9dbe8acd2b6114458f0498a617283d6275b","https://git.kernel.org/stable/c/bbf9ac34677b57506a13682b31a2a718934c0e31"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2024-36911","license":"CVE Program Terms of Use","key":"cve-program:CVE-2024-36911","identifiers":["CVE-2024-36911"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
