{"cve":"CVE-2026-23258","nvd":{"published":"2026-03-18T18:16:24.167","modified":"2026-06-17T10:21:12.127","status":"Analyzed","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: liquidio: Initialize netdev pointer before queue setup\n\nIn setup_nic_devices(), the netdev is allocated using alloc_etherdev_mq().\nHowever, the pointer to this structure is stored in oct->props[i].netdev\nonly after the calls to netif_set_real_num_rx_queues() and\nnetif_set_real_num_tx_queues().\n\nIf either of these functions fails, setup_nic_devices() returns an error\nwithout freeing the allocated netdev. Since oct->props[i].netdev is still\nNULL at this point, the cleanup function liquidio_destroy_nic_device()\nwill fail to find and free the netdev, resulting in a memory leak.\n\nFix this by initializing oct->props[i].netdev before calling the queue\nsetup functions. This ensures that the netdev is properly accessible for\ncleanup in case of errors.\n\nCompile tested only. Issue found using a prototype static analysis tool\nand code review.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-401"],"references":["https://git.kernel.org/stable/c/1d4590fde856cb94bd9a46e795c29d8288c238fc","https://git.kernel.org/stable/c/926ede0c85e1e57c97d64d9612455267d597bb2c","https://git.kernel.org/stable/c/a0e57c0b68c9e6f9a8fd7c1167861a5a730eb2f4","https://git.kernel.org/stable/c/be109646cdaecab262f6276303b1763468c94378","https://git.kernel.org/stable/c/c0ed6c77ec34050971fd0df2a94dfdea66d09331"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-23258","score":0.00119,"percentile":0.0173,"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).
