{"id":"CVE-2022-49478","summary":"media: pvrusb2: fix array-index-out-of-bounds in pvr2_i2c_core_init","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: pvrusb2: fix array-index-out-of-bounds in pvr2_i2c_core_init\n\nSyzbot reported that -1 is used as array index. The problem was in\nmissing validation check.\n\nhdw-\u003eunit_number is initialized with -1 and then if init table walk fails\nthis value remains unchanged. Since code blindly uses this member for\narray indexing adding sanity check is the easiest fix for that.\n\nhdw-\u003eworkpoll initialization moved upper to prevent warning in\n__flush_work.","modified":"2026-04-02T08:23:15.590286Z","published":"2025-02-26T02:13:19.330Z","related":["SUSE-SU-2025:01600-1","SUSE-SU-2025:1027-1","SUSE-SU-2025:1176-1","SUSE-SU-2025:1183-1","SUSE-SU-2025:1194-1","SUSE-SU-2025:1241-1","SUSE-SU-2025:1263-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49478.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1310fc3538dcc375a2f46ef0a438512c2ca32827"},{"type":"WEB","url":"https://git.kernel.org/stable/c/24e807541e4a9263ed928e6ae3498de3ad43bd1e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2e004fe914b243db41fa96f9e583385f360ea58e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3309c2c574e13b21b44729f5bdbf21f60189b79a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4351bfe36aba9fa7dc9d68d498d25d41a0f45e67"},{"type":"WEB","url":"https://git.kernel.org/stable/c/471bec68457aaf981add77b4f590d65dd7da1059"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a3304766d9384886e6d3092c776273526947a2e9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a3660e06675bccec4bf149c7229ea1d491ba10d7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f99a8b1ec0eddc2931aeaa4f490277a15b39f511"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49478.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49478"},{"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":"d855497edbfbf9e19a17f4a1154bca69cb4bd9ba"},{"fixed":"4351bfe36aba9fa7dc9d68d498d25d41a0f45e67"},{"fixed":"2e004fe914b243db41fa96f9e583385f360ea58e"},{"fixed":"a3660e06675bccec4bf149c7229ea1d491ba10d7"},{"fixed":"1310fc3538dcc375a2f46ef0a438512c2ca32827"},{"fixed":"a3304766d9384886e6d3092c776273526947a2e9"},{"fixed":"3309c2c574e13b21b44729f5bdbf21f60189b79a"},{"fixed":"f99a8b1ec0eddc2931aeaa4f490277a15b39f511"},{"fixed":"24e807541e4a9263ed928e6ae3498de3ad43bd1e"},{"fixed":"471bec68457aaf981add77b4f590d65dd7da1059"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-49478.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
