CVE-2023-52746

CVE-2023-52746 concerns a Spectre v1 gadget in the Linux kernel’s xfrm_xlate32_attr() path. The vulnerability arises from using the user-provided nla_type as an array index when type > XFRMA_MAX, potentially leaking kernel memory. The patch set introduces array_index_nospec() use to prevent sp...

CVE-2021-47277

CVE-2021-47277 affects the Linux kernel KVM path for guest memory translation. The issue arises when speculative execution may use an invalid guest frame number (gfn) to compute an out-of-bounds host virtual address (hva) in __gfn_to_hva_memslot, enabling a potential two-read Spectre gadget where...
