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-2022-50102 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2022-50102/ (Markdown: https://insights.sbomify.com/CVE-2022-50102/index.md)","id":"CVE-2022-50102","markdown":"https://insights.sbomify.com/CVE-2022-50102/index.md","name":"CVE-2022-50102","record":{"aliases":["DEBIAN-CVE-2022-50102","GHSA-4q34-pqwj-3cv6","UBUNTU-CVE-2022-50102"],"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 divide-by-zero error in the Linux kernel's arkfb driver via ioctl, causing a system crash.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-369","name":"Divide By Zero"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nvideo: fbdev: arkfb: Fix a divide-by-zero bug in ark_set_pixclock()\n\nSince the user can control the arguments of the ioctl() from the user\nspace, under special arguments that may result in a divide-by-zero bug\nin:\n  drivers/video/fbdev/arkfb.c:784: ark_set_pixclock(info, (hdiv * info-\u003evar.pixclock) / hmul);\nwith hdiv=1, pixclock=1 and hmul=2 you end up with (1*1)/2 = (int) 0.\nand then in:\n  drivers/video/fbdev/arkfb.c:504: rv = dac_set_freq(par-\u003edac, 0, 1000000000 / pixclock);\nwe'll get a division-by-zero.\n\nThe following log can reveal it:\n\ndivide error: 0000 [#1] PREEMPT SMP KASAN PTI\nRIP: 0010:ark_set_pixclock drivers/video/fbdev/arkfb.c:504 [inline]\nRIP: 0010:arkfb_set_par+0x10fc/0x24c0 drivers/video/fbdev/arkfb.c:784\nCall Trace:\n fb_set_var+0x604/0xeb0 drivers/video/fbdev/core/fbmem.c:1034\n do_fb_ioctl+0x234/0x670 drivers/video/fbdev/core/fbmem.c:1110\n fb_ioctl+0xdd/0x130 drivers/video/fbdev/core/fbmem.c:1189\n\nFix this by checking the argument of ark_set_pixclock() first.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"video: fbdev: arkfb: Fix a divide-by-zero bug in ark_set_pixclock()","id":"CVE-2022-50102","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"denial_of_service","year":"2022"},"n_packages":0,"n_references":8,"next":{"headline":"sched, cpuset: Fix dl_cpu_busy() panic due to empty cs-\u003ecpus_allowed","id":"CVE-2022-50103"},"packages":[],"prev":{"headline":"video: fbdev: vt8623fb: Check the size of screen before memset_io()","id":"CVE-2022-50101"},"products":["Linux"],"published":"2025-06-18","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A local attacker can trigger a divide-by-zero error in the Linux kernel's arkfb driver via ioctl, causing a system crash.","url":"https://insights.sbomify.com/CVE-2022-50102/"}
