The bd_cnt field has 5 bits and the maximum number\nsupported is 32 with the value 0.\n\nCONFIG_MAX_SKB_FRAGS can be modified and the total number of SKB\nfragments can approach or exceed the maximum supported by the chip.\nAdd a macro to properly mask the bd_cnt field so that the value 32\nwill be properly masked and set to 0 in the bd_cnd field.\n\nWithout this patch, the out-of-range bd_cnt value will corrupt the\nTX BD and may cause TX timeout.\n\nThe next patch will check for values exceeding 32.","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":[],"references":["https://git.kernel.org/stable/c/107b25db61122d8f990987895c2912927b8b6e3f","https://git.kernel.org/stable/c/9ee185e0f15594017a6f1a191ebe6630cfea5f74","https://git.kernel.org/stable/c/f60b41b815826f15c4d0323f923f398c423178d0"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:01:11.054312287+00:00"},"epss":{"cve":"CVE-2025-22108","score":0.00369,"percentile":0.30749,"date":"2026-11-01"},"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).
