{"id":"CVE-2026-46232","summary":"HID: playstation: Clamp num_touch_reports","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nHID: playstation: Clamp num_touch_reports\n\nA device would never lie about the number of touch reports would it?\n\nIf it does the loop in dualshock4_parse_report will read off the end of\nthe touch_reports array, up to about 2 KiB for the maximum number of 256\nloop iteraions. The data that is read is emitted via evdev if the\nDS4_TOUCH_POINT_INACTIVE bit happens to be set. Protect against this by\nclamping the num_touch_reports value provided by the device to the\nmaximum size of the touch_reports array.","modified":"2026-07-08T08:02:18.238802485Z","published":"2026-05-28T09:40:54.248Z","related":["openSUSE-SU-2026:10954-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46232.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0bc4cf1a6ba00fb8c074531b179bc7b97502fbc4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/208f6d5b1dfd6399bc6af9e11f27f1f496243ed0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7812694752a5f295eaa05a093b90a2c332666051"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9c031b24aed6733b6dcc5d98527875b8654a04e9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cac61b58a3b6340c52afa06bb15eac033158db2f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46232.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46232"},{"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":"752038248808a7ff176bbdb668f19ae7d2a9816b"},{"fixed":"0bc4cf1a6ba00fb8c074531b179bc7b97502fbc4"},{"fixed":"9c031b24aed6733b6dcc5d98527875b8654a04e9"},{"fixed":"7812694752a5f295eaa05a093b90a2c332666051"},{"fixed":"208f6d5b1dfd6399bc6af9e11f27f1f496243ed0"},{"fixed":"cac61b58a3b6340c52afa06bb15eac033158db2f"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46232.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.140"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.90"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.32"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46232.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H"}]}
