{"id":"CVE-2025-22104","summary":"ibmvnic: Use kernel helpers for hex dumps","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nibmvnic: Use kernel helpers for hex dumps\n\nPreviously, when the driver was printing hex dumps, the buffer was cast\nto an 8 byte long and printed using string formatters. 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  \u003c...\u003e\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  \u003c...\u003e\n  Allocated by task 17681:\n  \u003c...\u003e\n  ibmvnic_login+0x2f0/0xffc [ibmvnic]\n  ibmvnic_open+0x148/0x308 [ibmvnic]\n  __dev_open+0x1ac/0x304\n  \u003c...\u003e\n  The buggy address is located 168 bytes inside of\n                allocated 175-byte region [c0000001331a9a00, c0000001331a9aaf)\n  \u003c...\u003e\n  =================================================================\n  ibmvnic 30000003 env3: 000000000033766e","modified":"2026-04-02T12:45:21.243609Z","published":"2025-04-16T14:12:53.118Z","related":["ALSA-2025:9302","ALSA-2025:9896","CGA-pjhc-52m2-fjfp","SUSE-SU-2025:01614-1","SUSE-SU-2025:01707-1","SUSE-SU-2025:01919-1","SUSE-SU-2025:01951-1","SUSE-SU-2025:01964-1","SUSE-SU-2025:01967-1","SUSE-SU-2025:01972-1","SUSE-SU-2025:01983-1","SUSE-SU-2025:20343-1","SUSE-SU-2025:20344-1","SUSE-SU-2025:20354-1","SUSE-SU-2025:20355-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/22xxx/CVE-2025-22104.json"},"references":[{"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"032c5e82847a2214c3196a90f0aeba0ce252de58"},{"fixed":"ae6b1d6c1acee3a2000394d83ec9f1028321e207"},{"fixed":"d93a6caab5d7d9b5ce034d75b1e1e993338e3852"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-22104.json"}}],"schema_version":"1.7.5"}
