However, the netdev lock has already been\nacquired before ndo_bpf is called because GVE supports queue management\nops. Calling the unlocked versions of napi_disable/enable results in a\ndeadlock when attempting to disable XSK pools, as the thread attempts to\nre-acquire a lock it already holds.\n\nUpdate the NAPI calls to use the locked versions.\n\nThis issue was found in production.","state":0,"publishedAt":"2026-10-23T12:22:13.825+00:00","modifiedAt":"2026-10-23T12:22:13.825+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/ethernet/google/gve/gve_main.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"606048cbd8346e616cfaee01b0143d072534136d\",\n                            \"lessThan\": \"42935a61001927aa01db10b53b420efd37eaa99b\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"606048cbd8346e616cfaee01b0143d072534136d\",\n                            \"lessThan\": \"3d377911ce81fd4e61af814e750d8e08879a5208\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"606048cbd8346e616cfaee01b0143d072534136d\",\n                            \"lessThan\": \"0cb6939a4dfefa822007b7a71986e06bc4f61f54\",\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/ethernet/google/gve/gve_main.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.16\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.16\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.57\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.11\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/42935a61001927aa01db10b53b420efd37eaa99b","https://git.kernel.org/stable/c/3d377911ce81fd4e61af814e750d8e08879a5208","https://git.kernel.org/stable/c/0cb6939a4dfefa822007b7a71986e06bc4f61f54"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-99048","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-99048","identifiers":["CVE-2026-99048"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
