But if the fallback happens more than once, then the\ncopies of these callback functions will be overwritten incorrectly,\nresulting in a loop call issue:\n\nclcsk->sk_error_report\n |- smc_fback_error_report() <------------------------------|\n     |- smc_fback_forward_wakeup()                          | (loop)\n         |- clcsock_callback()  (incorrectly overwritten)   |\n             |- smc->clcsk_error_report() ------------------|\n\nSo this patch fixes the issue by saving these function pointers only\nonce in the fallback and avoiding overwriting.","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-835"],"references":["https://git.kernel.org/stable/c/1de9770d121ee9294794cca0e0be8fbfa0134ee8","https://git.kernel.org/stable/c/7de7ba7a8bd4fde0141de8674c13514d0072f0e6","https://git.kernel.org/stable/c/f00b6c976ae0dfbd9b891175f713f59095d23842","https://git.kernel.org/stable/c/1de9770d121ee9294794cca0e0be8fbfa0134ee8","https://git.kernel.org/stable/c/7de7ba7a8bd4fde0141de8674c13514d0072f0e6"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:52:42.518321223+00:00"},"epss":{"cve":"CVE-2022-48780","score":0.00227,"percentile":0.13463,"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).
