The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. This vulnerability allows a local attacker to escalate privileges and execute arbitrary code in the context of the kernel. The attacker must first obtain the ability to execute high-privileged code on the target system to exploit this vulnerability.","state":"PUBLIC","assigner":"secalert@redhat.com","published_at":"2022-08-25 18:15:00","updated_at":"2022-08-30 20:31:00"},"problem_types":["CWE-787"],"metrics":[],"references":[{"url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/lightnvm/Kconfig?h=v5.10.114&id=549209caabc89f2877ad5f62d11fca5c052e0e8","name":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/lightnvm/Kconfig?h=v5.10.114&id=549209caabc89f2877ad5f62d11fca5c052e0e8","refsource":"MISC","tags":[],"title":"kernel/git/stable/linux.git - Linux kernel stable tree","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.zerodayinitiative.com/advisories/ZDI-22-960/","name":"https://www.zerodayinitiative.com/advisories/ZDI-22-960/","refsource":"MISC","tags":[],"title":"ZDI-22-960 | Zero Day Initiative","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.cve.org/CVERecord?id=CVE-2022-2991","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2022-2991","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2022","cve_id":"2991","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"o","cpe4":"linux","cpe5":"linux_kernel","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[{"cve":"CVE-2022-2991","qid":"180966","title":"Debian Security Update for linux (CVE-2022-2991)"},{"cve":"CVE-2022-2991","qid":"199560","title":"Ubuntu Security Notification for Linux kernel (AWS) Vulnerabilities (USN-6001-1)"},{"cve":"CVE-2022-2991","qid":"199568","title":"Ubuntu Security Notification for Linux kernel (AWS) Vulnerabilities (USN-6013-1)"},{"cve":"CVE-2022-2991","qid":"199577","title":"Ubuntu Security Notification for Linux kernel Vulnerabilities (USN-6014-1)"},{"cve":"CVE-2022-2991","qid":"672454","title":"EulerOS Security Update for kernel (EulerOS-SA-2022-2848)"},{"cve":"CVE-2022-2991","qid":"672474","title":"EulerOS Security Update for kernel (EulerOS-SA-2022-2823)"},{"cve":"CVE-2022-2991","qid":"753745","title":"SUSE Enterprise Linux Security Update for the Linux Kernel (SUSE-SU-2023:0634-1)"},{"cve":"CVE-2022-2991","qid":"753807","title":"SUSE Enterprise Linux Security Update for the Linux Kernel (SUSE-SU-2023:0768-1)"},{"cve":"CVE-2022-2991","qid":"753832","title":"SUSE Enterprise Linux Security Update for the Linux Kernel (SUSE-SU-2023:0852-1)"},{"cve":"CVE-2022-2991","qid":"903749","title":"Common Base Linux Mariner (CBL-Mariner) Security Update for kernel (10706)"},{"cve":"CVE-2022-2991","qid":"904203","title":"Common Base Linux Mariner (CBL-Mariner) Security Update for kernel (10706-1)"},{"cve":"CVE-2022-2991","qid":"905922","title":"Common Base Linux Mariner (CBL-Mariner) Security Update for kernel (10706-2)"}]},"source_records":{"cve_program":{"data_type":"CVE","data_format":"MITRE","data_version":"4.0","CVE_data_meta":{"ID":"CVE-2022-2991","ASSIGNER":"secalert@redhat.com","STATE":"PUBLIC"},"affects":{"vendor":{"vendor_data":[{"vendor_name":"n/a","product":{"product_data":[{"product_name":"kernel","version":{"version_data":[{"version_value":"Fixed in kernel 5.15-rc1"}]}}]}}]}},"problemtype":{"problemtype_data":[{"description":[{"lang":"eng","value":"CWE-122"}]}]},"references":{"reference_data":[{"refsource":"MISC","name":"https://www.zerodayinitiative.com/advisories/ZDI-22-960/","url":"https://www.zerodayinitiative.com/advisories/ZDI-22-960/"},{"refsource":"MISC","name":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/lightnvm/Kconfig?h=v5.10.114&id=549209caabc89f2877ad5f62d11fca5c052e0e8","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/lightnvm/Kconfig?h=v5.10.114&id=549209caabc89f2877ad5f62d11fca5c052e0e8"}]},"description":{"description_data":[{"lang":"eng","value":"A heap-based buffer overflow was found in the Linux kernel's LightNVM subsystem.
