It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-38198 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-38198/ (Markdown: https://insights.sbomify.com/CVE-2025-38198/index.md)","id":"CVE-2025-38198","markdown":"https://insights.sbomify.com/CVE-2025-38198/index.md","name":"CVE-2025-38198","record":{"aliases":["AZL-64662","AZL-72769","BELL-CVE-2025-38198","DEBIAN-CVE-2025-38198","GHSA-2v92-8hh5-248m","ROOT-OS-DEBIAN-11-CVE-2025-38198","ROOT-OS-DEBIAN-12-CVE-2025-38198","ROOT-OS-UBUNTU-2204-CVE-2025-38198","ROOT-OS-UBUNTU-2404-CVE-2025-38198","UBUNTU-CVE-2025-38198"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A local attacker can trigger a kernel crash by writing to a sysfs node when a console is unregistered, causing a denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-129","name":"Improper Validation of Array Index"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nfbcon: Make sure modelist not set on unregistered console\n\nIt looks like attempting to write to the \"store_modes\" sysfs node will\nrun afoul of unregistered consoles:\n\nUBSAN: array-index-out-of-bounds in drivers/video/fbdev/core/fbcon.c:122:28\nindex -1 is out of range for type 'fb_info *[32]'\n...\n fbcon_info_from_console+0x192/0x1a0 drivers/video/fbdev/core/fbcon.c:122\n fbcon_new_modelist+0xbf/0x2d0 drivers/video/fbdev/core/fbcon.c:3048\n fb_new_modelist+0x328/0x440 drivers/video/fbdev/core/fbmem.c:673\n store_modes+0x1c9/0x3e0 drivers/video/fbdev/core/fbsysfs.c:113\n dev_attr_store+0x55/0x80 drivers/base/core.c:2439\n\nstatic struct fb_info *fbcon_registered_fb[FB_MAX];\n...\nstatic signed char con2fb_map[MAX_NR_CONSOLES];\n...\nstatic struct fb_info *fbcon_info_from_console(int console)\n...\n        return fbcon_registered_fb[con2fb_map[console]];\n\nIf con2fb_map contains a -1 things go wrong here.
