CLEANSTART-2024-EC26325 When SMT is enabled, certain AMD processors may speculatively execute instructions using a target from the sibling thread after an SMT mode switch potentially resulting in information disclosure
Security vulnerability affects the xen package. When SMT is enabled, certain AMD processors may speculatively execute instructions using a target from the sibling thread after an SMT mode switch potentially resulting in information disclosure...
CVE-2026-98729
A flaw was found in the Linux kernel. On systems utilizing specific AMD processors, improper virtual address alignment for huge page memory mappings can allow a local user to cause a Denial of Service DoS. When unmapping these misaligned memory ranges during teardown, the kernel encounters an...
