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","affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"032c5e82847a2214c3196a90f0aeba0ce252de58"},{"fixed":"19efa170e01207c8ada726f3f6c65b31fcba2a73"},{"fixed":"9bc078818ec76344c2e06b81d7aee2df3adecfbf"},{"fixed":"005fee039dd845122d313ac8f2122b0d09dc5d7b"},{"fixed":"ae6b1d6c1acee3a2000394d83ec9f1028321e207"},{"fixed":"d93a6caab5d7d9b5ce034d75b1e1e993338e3852"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-22104.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.5.0"},{"fixed":"6.1.187"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.156"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.108"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.14.2"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-22104.json"}}],"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/005fee039dd845122d313ac8f2122b0d09dc5d7b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/19efa170e01207c8ada726f3f6c65b31fcba2a73"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9bc078818ec76344c2e06b81d7aee2df3adecfbf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ae6b1d6c1acee3a2000394d83ec9f1028321e207"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d93a6caab5d7d9b5ce034d75b1e1e993338e3852"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/22xxx/CVE-2025-22104.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-22104"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/22xxx/CVE-2025-22104.json"}}
