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-2022-48997 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-2022-48997/ (Markdown: https://insights.sbomify.com/CVE-2022-48997/index.md)","id":"CVE-2022-48997","markdown":"https://insights.sbomify.com/CVE-2022-48997/index.md","name":"CVE-2022-48997","record":{"aliases":["DEBIAN-CVE-2022-48997","GHSA-vch3-xc23-jrf2","UBUNTU-CVE-2022-48997"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel TPM driver","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel TPM suspend function can cause system errors and potential denial of service during power management events.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":4.7,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nchar: tpm: Protect tpm_pm_suspend with locks\n\nCurrently tpm transactions are executed unconditionally in\ntpm_pm_suspend() function, which may lead to races with other tpm\naccessors in the system.\n\nSpecifically, the hw_random tpm driver makes use of tpm_get_random(),\nand this function is called in a loop from a kthread, which means it's\nnot frozen alongside userspace, and so can race with the work done\nduring system suspend:\n\n  tpm tpm0: tpm_transmit: tpm_recv: error -52\n  tpm tpm0: invalid TPM_STS.x 0xff, dumping stack for forensics\n  CPU: 0 PID: 1 Comm: init Not tainted 6.1.0-rc5+ #135\n  Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.0-20220807_005459-localhost 04/01/2014\n  Call Trace:\n   tpm_tis_status.cold+0x19/0x20\n   tpm_transmit+0x13b/0x390\n   tpm_transmit_cmd+0x20/0x80\n   tpm1_pm_suspend+0xa6/0x110\n   tpm_pm_suspend+0x53/0x80\n   __pnp_bus_suspend+0x35/0xe0\n   __device_suspend+0x10f/0x350\n\nFix this by calling tpm_try_get_ops(), which itself is a wrapper around\ntpm_chip_start(), but takes the appropriate mutex.\n\n[Jason: reworked commit message, added metadata]","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":"char: tpm: Protect tpm_pm_suspend with locks","id":"CVE-2022-48997","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"race_condition","year":"2022"},"n_packages":0,"n_references":5,"next":{"headline":"powerpc/bpf/32: Fix Oops on tail call tests","id":"CVE-2022-48998"},"packages":[],"prev":{"headline":"mm/damon/sysfs: fix wrong empty schemes assumption under online tuning in damon_sysfs_set_schemes()","id":"CVE-2022-48996"},"products":["Linux"],"published":"2024-10-21","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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A race condition in the Linux kernel TPM suspend function can cause system errors and potential denial of service during power management events.","url":"https://insights.sbomify.com/CVE-2022-48997/"}
