If the allocation fails, nothing is\nreposted. Every failure therefore takes one buffer out of the RX queue\nwhile the interface remains up, and enough failures eventually stall\nreception.\n\nA retry path could refill the queue later, but ntb_netdev has none.\nAllocate the replacement first instead. If that fails, drop the packet\nand repost the same skb. This keeps the queue full and lets packet\ndelivery resume as soon as memory is available again.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":[],"references":["https://git.kernel.org/stable/c/18781cc0bfb5c7f2a51ac6d678a28f101b7c35c5","https://git.kernel.org/stable/c/272df0fbe6f3e04e22bc67fbdd9ac24586b942f4","https://git.kernel.org/stable/c/3f2a15f33f86f7bd5b920669fd40c06725d72a1e","https://git.kernel.org/stable/c/6d7f8a23c130d768c0976c2578b214353674e18f","https://git.kernel.org/stable/c/755fd7843f300d724caceabdf9bb13adc8701540"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-74626","score":0.00501,"percentile":0.42623,"date":"2026-10-25"},"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).
