If the buffer\nsize was not a multiple of 8 then a read buffer overflow was possible.\n\nTherefore, create a new ibmvnic function that loops over a buffer and\ncalls hex_dump_to_buffer instead.\n\nThis patch address KASAN reports like the one below:\n  ibmvnic 30000003 env3: Login Buffer:\n  ibmvnic 30000003 env3: 01000000af000000\n  <...>\n  ibmvnic 30000003 env3: 2e6d62692e736261\n  ibmvnic 30000003 env3: 65050003006d6f63\n  ==================================================================\n  BUG: KASAN: slab-out-of-bounds in ibmvnic_login+0xacc/0xffc [ibmvnic]\n  Read of size 8 at addr c0000001331a9aa8 by task ip/17681\n  <...>\n  Allocated by task 17681:\n  <...>\n  ibmvnic_login+0x2f0/0xffc [ibmvnic]\n  ibmvnic_open+0x148/0x308 [ibmvnic]\n  __dev_open+0x1ac/0x304\n  <...>\n  The buggy address is located 168 bytes inside of\n                allocated 175-byte region [c0000001331a9a00, c0000001331a9aaf)\n  <...>\n  =================================================================\n  ibmvnic 30000003 env3: 000000000033766e","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","score":7.1},"cwes":["CWE-125"],"references":["https://git.kernel.org/stable/c/005fee039dd845122d313ac8f2122b0d09dc5d7b","https://git.kernel.org/stable/c/19efa170e01207c8ada726f3f6c65b31fcba2a73","https://git.kernel.org/stable/c/9bc078818ec76344c2e06b81d7aee2df3adecfbf","https://git.kernel.org/stable/c/ae6b1d6c1acee3a2000394d83ec9f1028321e207","https://git.kernel.org/stable/c/d93a6caab5d7d9b5ce034d75b1e1e993338e3852"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:01:11.054312287+00:00"},"epss":{"cve":"CVE-2025-22104","score":0.00229,"percentile":0.13716,"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).
