{"id":"DEBIAN-CVE-2023-54167","details":"In the Linux kernel, the following vulnerability has been resolved:  m68k: mm: Move initrd phys_to_virt handling after paging_init()  When booting with an initial ramdisk on platforms where physical memory does not start at address zero (e.g. on Amiga):      initrd: 0ef0602c - 0f800000     Zone ranges:       DMA      [mem 0x0000000008000000-0x000000f7ffffffff]       Normal   empty     Movable zone start for each node     Early memory node ranges       node   0: [mem 0x0000000008000000-0x000000000f7fffff]     Initmem setup node 0 [mem 0x0000000008000000-0x000000000f7fffff]     Unable to handle kernel access at virtual address (ptrval)     Oops: 00000000     Modules linked in:     PC: [\u003c00201d3c\u003e] memcmp+0x28/0x56  As phys_to_virt() relies on m68k_memoffset and module_fixup(), it must not be called before paging_init().  Hence postpone the phys_to_virt handling for the initial ramdisk until after calling paging_init().  While at it, reduce #ifdef clutter by using IS_ENABLED() instead.","modified":"2026-09-15T08:47:44.931259730Z","published":"2025-12-30T13:16:04.503Z","upstream":["CVE-2023-54167"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2023-54167"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.20-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54167.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.20-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54167.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.20-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-54167.json"}}],"schema_version":"1.9.0"}
