On error the original value is not restored, and the reference is put for the file to which vm_file points. On upstream kernels this is not an issue, as no callers dereference vm_file following after call_mmap() returns an error. However, the aufs patchs change mmap_region() to replace the fput() using a local variable with vma_fput(), which will fput() vm_file, leading to a refcount underflow.",null,[],[],[],[14],{"_key":15},"CVE-2019-15794",[],[],[],"2020-04-24T00:15:11.933Z","2026-04-28T20:20:21.574379Z",{"cisa_kev":22,"cisa_ransomware":22,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":9,"severity_score":9,"severity_version":9,"severity_source":9,"severity_vector":9,"severity_status":9},false,[24],{"url":25,"sources":26,"tags":28},"https://security-tracker.debian.org/tracker/CVE-2019-15794",[27],"osv_debian",[29],"Advisory",[],[],[33],{"source":27,"cvss_v2_0":9,"cvss_v3_0":9,"cvss_v3_1":34,"cvss_v4_0":9},{"baseScore":35,"baseSeverity":9,"vectorString":36,"impactScore":37,"exploitabilityScore":38},6.7,"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H",9.8,2.1,[40],{"ecosystem":41,"name":42,"vendor":43,"product":42,"cpe_part":9,"purl_type":44,"purl_namespace":43,"purl_name":42,"source":9,"versions":45},"Debian","linux","debian","deb",[46,50,54,55],{"version":47,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":9,"version_end_type":9,"fixed_in":9},"all",true,"ecosystem",{"version":51,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":52,"version_end_type":53,"fixed_in":9},"lt5_16_7_1","5.16.7-1","excluding",{"version":51,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":52,"version_end_type":53,"fixed_in":9},{"version":51,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":52,"version_end_type":53,"fixed_in":9}]
