Severity ?
8.4 (High) - CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: of: reserved_mem: prevent OOB when too many dynamic regions are defined On boot, fdt_scan_reserved_mem() saves each dynamically-placed /reserved-memory subnode into a local array of size MAX_RESERVED_REGIONS. If the device tree defines more than MAX_RESERVED_REGIONS dynamically-placed regions, fdt_scan_reserved_mem() writes past the end of the local array. Add a bounds check that logs an error and skips the excess regions, restoring the original behavior.

unprivileged local users and user-namespace capabilities cannot reach this __init-only path.\\nUI:N - Once a malicious DTB is installed, the stack overflow occurs automatically during early_init_fdt_scan_reserved_mem() before userspace starts; no cooperative action by another user or administrator is required beyond normal boot.\\nS:U - Impact is confined to early-boot kernel stack/memory corruption within the same host kernel; this is not a VM escape, guest-to-host breakout, IOMMU boundary bypass, or other cross-security-authority scenario.\\nC:H - Each OOB store writes an attacker-influenced FDT node offset past dynamic_nodes[MAX_RESERVED_REGIONS] onto the kernel stack, corrupting adjacent locals and potentially frame/link registers; per kernel guidance, stack OOB writes enable high confidentiality impact.\\nI:H - This is a stack buffer overflow (CWE-121/787) during __init: repeated int writes past the 64-element dynamic_nodes[] array can corrupt return addresses and control flow in early boot before full hardening, enabling arbitrary kernel code execution.\\nA:H - Unchecked OOB writes into the boot-time stack typically cause immediate kernel panic/oops during fdt_scan_reserved_mem() (corrupted count/fdt pointers or trashed frame), denying availability on every boot with a crafted or over-limit DT.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"9a0fe62f93ede02c27aaca81112af1e59c8c0979\", \"lessThan\": \"68d27250c9e81ab7764603e346c2b1017cb53adf\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"8a6e02d0c00e7b62e6acb74146878bb91e9e7e31\", \"lessThan\": \"cfa7e2734877330d6c10e0f33953905486c4530c\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"8a6e02d0c00e7b62e6acb74146878bb91e9e7e31\", \"lessThan\": \"de8ccbd6bf4efe7a059e2c483789936009e10f42\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"8a6e02d0c00e7b62e6acb74146878bb91e9e7e31\", \"lessThan\": \"db3dbdfea1b8f38774419c5c2c14e4b81c48708d\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"6.12.13\", \"lessThan\": \"6.12.103\", \"versionType\": \"semver\"}], \"programFiles\": [\"drivers/of/of_reserved_mem.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"6.13\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"6.13\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.12.103\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.44\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.1.8\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.1.*\"}, {\"status\": \"unaffected\", \"version\": \"7.2\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/of/of_reserved_mem.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/68d27250c9e81ab7764603e346c2b1017cb53adf\"}, {\"url\": \"https://git.kernel.org/stable/c/cfa7e2734877330d6c10e0f33953905486c4530c\"}, {\"url\": \"https://git.kernel.org/stable/c/de8ccbd6bf4efe7a059e2c483789936009e10f42\"}, {\"url\": \"https://git.kernel.org/stable/c/db3dbdfea1b8f38774419c5c2c14e4b81c48708d\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nof: reserved_mem: prevent OOB when too many dynamic regions are defined\\n\\nOn boot, fdt_scan_reserved_mem() saves each dynamically-placed\\n/reserved-memory subnode into a local array of size\\nMAX_RESERVED_REGIONS.\\n\\nIf the device tree defines more than MAX_RESERVED_REGIONS\\ndynamically-placed regions, fdt_scan_reserved_mem() writes past the\\nend of the local array.\\n\\nAdd a bounds check that logs an error and skips the excess regions,\\nrestoring the original behavior.\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.12.103\", \"versionStartIncluding\": \"6.12.13\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.18.44\", \"versionStartIncluding\": \"6.13\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"7.1.8\", \"versionStartIncluding\": \"6.13\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"7.2\", \"versionStartIncluding\": \"6.13\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2026-08-29T06:22:40.126Z\"}}}",
