CVE-2021-47623

CVE-2021-47623 affects the PowerPC path in the Linux kernel where unmapping a fixmap entry via __set_fixmap() (FIXMAP_PAGE_CLEAR) ends up calling map_kernel_page(), which fails if invoked a second time for the same page. The connected documents confirm the root cause in arch/powerpc/mm/pgtable.c ...

CVE-2024-40974

CVE-2024-40974 (Linux kernel, powerpc/pseries) is a local concern where plpar_hcall() and plpar_hcall9() expect valid, explicitly-sized result buffers; historically, only in-code comments signaled minimum sizes, risking stack corruption when a caller used undersized buffers. The affected code now...
