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-2022-49468 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-2022-49468/ (Markdown: https://insights.sbomify.com/CVE-2022-49468/index.md)","id":"CVE-2022-49468","markdown":"https://insights.sbomify.com/CVE-2022-49468/index.md","name":"CVE-2022-49468","record":{"aliases":["DEBIAN-CVE-2022-49468","GHSA-2vp4-6vg4-qh8r","UBUNTU-CVE-2022-49468"],"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 memory leak in the Linux kernel thermal core allows attackers to cause denial of service by triggering device registration failures.","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":"cisa-adp","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-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nthermal/core: Fix memory leak in __thermal_cooling_device_register()\n\nI got memory leak as follows when doing fault injection test:\n\nunreferenced object 0xffff888010080000 (size 264312):\n  comm \"182\", pid 102533, jiffies 4296434960 (age 10.100s)\n  hex dump (first 32 bytes):\n    00 00 00 00 ad 4e ad de ff ff ff ff 00 00 00 00  .....N..........\n    ff ff ff ff ff ff ff ff 40 7f 1f b9 ff ff ff ff  ........@.......\n  backtrace:\n    [\u003c0000000038b2f4fc\u003e] kmalloc_order_trace+0x1d/0x110 mm/slab_common.c:969\n    [\u003c00000000ebcb8da5\u003e] __kmalloc+0x373/0x420 include/linux/slab.h:510\n    [\u003c0000000084137f13\u003e] thermal_cooling_device_setup_sysfs+0x15d/0x2d0 include/linux/slab.h:586\n    [\u003c00000000352b8755\u003e] __thermal_cooling_device_register+0x332/0xa60 drivers/thermal/thermal_core.c:927\n    [\u003c00000000fb9f331b\u003e] devm_thermal_of_cooling_device_register+0x6b/0xf0 drivers/thermal/thermal_core.c:1041\n    [\u003c000000009b8012d2\u003e] max6650_probe.cold+0x557/0x6aa drivers/hwmon/max6650.c:211\n    [\u003c00000000da0b7e04\u003e] i2c_device_probe+0x472/0xac0 drivers/i2c/i2c-core-base.c:561\n\nIf device_register() fails, thermal_cooling_device_destroy_sysfs() need be called\nto free the memory allocated in thermal_cooling_device_setup_sysfs().","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":"thermal/core: Fix memory leak in __thermal_cooling_device_register()","id":"CVE-2022-49468","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":5,"next":{"headline":"btrfs: fix anon_dev leak in create_subvol()","id":"CVE-2022-49469"},"packages":[],"prev":{"headline":"drm: msm: fix possible memory leak in mdp5_crtc_cursor_set()","id":"CVE-2022-49467"},"products":["Linux"],"published":"2025-02-26","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A memory leak in the Linux kernel thermal core allows attackers to cause denial of service by triggering device registration failures.","url":"https://insights.sbomify.com/CVE-2022-49468/"}
