CVE-2021-47580 is fixed in 39 products on 1 platform, first by RHSA-2022:7683, released November 8, 2022. It is not reported as exploited. Patch Radar priority: High. - Web page: https://patchblox.com/security/cve/CVE-2021-47580 - Priority: High - CVSS: 7.1 (high) - EPSS: 0.0024 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Nov 8, 2022 ## Description In the Linux kernel, the following vulnerability has been resolved: scsi: scsi_debug: Fix type in min_t to avoid stack OOB Change min_t() to use type "u32" instead of type "int" to avoid stack out of bounds. With min_t() type "int" the values get sign extended and the larger value gets used causing stack out of bounds.
