The simpler workaround\nthen created for alx driver, but not for atl1c due to lack of tester.\n\nInstead of using a custom allocator, check the allocated skb address and\nuse skb_reserve() to move away from problematic 0x...fc0 address.\n\nTested on AR8131 on Acer 4540.","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/32f08b7b430ee01ec47d730f961a3306c1c7b6fb","https://git.kernel.org/stable/c/54a6152da4993ec8e4b53dc3cf577f5a2c829afa","https://git.kernel.org/stable/c/57e44ff9c2c9747b2b1a53556810b0e5192655d6","https://git.kernel.org/stable/c/86565682e9053e5deb128193ea9e88531bbae9cf","https://git.kernel.org/stable/c/c29a89b23f67ee592f4dee61f9d7efbf86d60315"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:50:30.954589733+00:00"},"epss":{"cve":"CVE-2023-52834","score":0.00652,"percentile":0.51245,"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).
