It causes that kmemdup() returns ZERO_SIZE_PTR (0x10).\n\nThen the data_vault_read() got NULL point dereference problem when\naccessing the 0x10 value in data_vault.\n\n[   71.024560] BUG: kernel NULL pointer dereference, address:\n0000000000000010\n\nThis patch uses ZERO_OR_NULL_PTR() for checking ZERO_SIZE_PTR or\nNULL value in data_vault.","modified":"2026-04-11T12:41:17.066906Z","published":"2024-05-03T15:14:07.390Z","related":["SUSE-SU-2024:1644-1","SUSE-SU-2024:1659-1","SUSE-SU-2024:1663-1","SUSE-SU-2024:2011-1","SUSE-SU-2024:2189-1","SUSE-SU-2025:0231-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/48xxx/CVE-2022-48703.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/39d5137085a6c37ace4680ee4d24020a4a03e7dc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7931e28098a4c1a2a6802510b0cbe57546d2049d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dae42083b045a4ddf71c57cf350cb2412b5915c2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/48xxx/CVE-2022-48703.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-48703"},{"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":"0ba13c763aacb27ab32bde5d559bf40e88465921"},{"fixed":"39d5137085a6c37ace4680ee4d24020a4a03e7dc"},{"fixed":"dae42083b045a4ddf71c57cf350cb2412b5915c2"},{"fixed":"7931e28098a4c1a2a6802510b0cbe57546d2049d"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-48703.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.8.0"},{"fixed":"5.15.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"5.19.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-48703.json"}}],"schema_version":"1.7.5"}
