{"cve":"CVE-2024-53088","nvd":{"published":"2024-11-19T18:15:27.950","modified":"2026-08-04T11:21:49.180","status":"Modified","description":"In the Linux kernel, the following vulnerability has been resolved:\n\ni40e: fix race condition by adding filter's intermediate sync state\n\nFix a race condition in the i40e driver that leads to MAC/VLAN filters\nbecoming corrupted and leaking. Address the issue that occurs under\nheavy load when multiple threads are concurrently modifying MAC/VLAN\nfilters by setting mac and port VLAN.\n\n1. Thread T0 allocates a filter in i40e_add_filter() within\n        i40e_ndo_set_vf_port_vlan().\n2. Thread T1 concurrently frees the filter in __i40e_del_filter() within\n        i40e_ndo_set_vf_mac().\n3. Subsequently, i40e_service_task() calls i40e_sync_vsi_filters(), which\n        refers to the already freed filter memory, causing corruption.\n\nReproduction steps:\n1. Spawn multiple VFs.\n2. Apply a concurrent heavy load by running parallel operations to change\n        MAC addresses on the VFs and change port VLANs on the host.\n3. Observe errors in dmesg:\n\"Error I40E_AQ_RC_ENOSPC adding RX filters on VF XX,\n\tplease set promiscuous on manually for VF XX\".\n\nExact code for stable reproduction Intel can't open-source now.\n\nThe fix involves implementing a new intermediate filter state,\nI40E_FILTER_NEW_SYNC, for the time when a filter is on a tmp_add_list.\nThese filters cannot be deleted from the hash list directly but\nmust be removed using the full process.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","score":4.7},"cwes":["CWE-362"],"references":["https://git.kernel.org/stable/c/262dc6ea5f1eb18c4d08ad83d51222d0dd0dd42a","https://git.kernel.org/stable/c/6e046f4937474bc1b9fa980c1ad8f3253fc638f6","https://git.kernel.org/stable/c/7ad3fb3bfd43feb4e15c81dffd23ac4e55742791","https://git.kernel.org/stable/c/bf5f837d9fd27d32fb76df0a108babcaf4446ff1","https://git.kernel.org/stable/c/f30490e9695ef7da3d0899c6a0293cc7cd373567"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:57:34.731061660+00:00"},"epss":{"cve":"CVE-2024-53088","score":0.00187,"percentile":0.08392,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
