When that allocation fails the\nfunction returns the error directly, skipping the err_dealloc_rxbuffs\nlabel which is the only place that restores the previous pointer.\n\nThe attach is reported as failed, so the BPF core drops the reference it\nheld for the caller and the program can be freed, while apc->bpf_prog\nstill points at it. The next consumer of mana_xdp_get() - typically\nmana_chn_setxdp() from mana_alloc_queues() on the following ifup, or\nafter a TX timeout reset - then calls bpf_prog_add() on freed memory.\n\nThis is reachable from an ordinary \"ip link set dev ethX xdp obj ...\"\nwhenever the per-queue RX buffer pre-allocation cannot be satisfied.\n\nRestore the previous program on that error path.","state":0,"publishedAt":"2026-09-25T10:23:01.968+00:00","modifiedAt":"2026-10-19T09:11:21.414+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/microsoft/mana/mana_bpf.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"730ff06d3f5cc2ce0348414b78c10528b767d4a3\",\n                            \"lessThan\": \"5b3cdc9abd82b7e49e0f1a21d6eb75466c5ecef8\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"730ff06d3f5cc2ce0348414b78c10528b767d4a3\",\n                            \"lessThan\": \"9801edfba8dfcdb1da3b0afccdf143e13d646b56\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"730ff06d3f5cc2ce0348414b78c10528b767d4a3\",\n                            \"lessThan\": \"4c46beb807efcc93f5899ebe1f5958248eb296c6\",\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/microsoft/mana/mana_bpf.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.18\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.18\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.53\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.7\",\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/5b3cdc9abd82b7e49e0f1a21d6eb75466c5ecef8","https://git.kernel.org/stable/c/9801edfba8dfcdb1da3b0afccdf143e13d646b56","https://git.kernel.org/stable/c/4c46beb807efcc93f5899ebe1f5958248eb296c6"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-97955","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-97955","identifiers":["CVE-2026-97955"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
