{"id":"CVE-2026-53202","summary":"accel/ivpu: Fix signed integer truncation in IPC receive","details":"In the Linux kernel, the following vulnerability has been resolved:\n\naccel/ivpu: Fix signed integer truncation in IPC receive\n\nFix potential buffer overflow where firmware-supplied data_size is cast\nto signed int before being used in min_t(). Large unsigned values\n(\u003e= 0x80000000) become negative, causing unsigned wraparound and\noversized memcpy operations that can overflow the stack buffer.\n\nChange min_t(int, ...) to min() as both values are unsigned and can be\nhandled by min() without explicit cast.","modified":"2026-07-08T08:07:24.277062757Z","published":"2026-06-25T08:39:10.287Z","related":["CGA-hqr5-fm36-mmv8"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53202.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2821bf2b79e47f87e1dbdd9d25c78240965a97d6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/45cb105b8642c65e9be286f7058e92314efe7ea3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4788556d4dd9d717037e385de178974e9649231d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d9faef564438d1e4579c692c046603e7ada7bdf4"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-53202.json"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-53202"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53202.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53202"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2492823"},{"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":"3b434a3445fff3149128db0169da864d67057325"},{"fixed":"4788556d4dd9d717037e385de178974e9649231d"},{"fixed":"45cb105b8642c65e9be286f7058e92314efe7ea3"},{"fixed":"2821bf2b79e47f87e1dbdd9d25c78240965a97d6"},{"fixed":"d9faef564438d1e4579c692c046603e7ada7bdf4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53202.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.8.0"},{"fixed":"6.12.94"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.36"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.13"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53202.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"}]}
