To simply fix it, we could just pass @sign kmalloc'd from crypt_message() and then we're done.  Luckily, we don't seem to pass any other vmalloc'd buffers in smb_rqst::rq_iov...  Instead, let's map the correct pages and offsets from vmalloc buffers as well in cifs_sg_set_buf() and then avoiding such oopses.",null,[],[],[],[14],{"_key":15},"CVE-2022-50341",[],[],[],"2025-09-16T17:15:33.660Z","2026-04-28T20:25:34.023227Z",{"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-2022-50341",[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},5.5,"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H",6,4.6,[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",[46,52,55,56],{"version":47,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":50,"version_end_type":51,"fixed_in":9},"lt5_10_178_1",true,"ecosystem","5.10.178-1","excluding",{"version":53,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":54,"version_end_type":51,"fixed_in":9},"lt6_1_4_1","6.1.4-1",{"version":53,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":54,"version_end_type":51,"fixed_in":9},{"version":53,"is_range":48,"range_type":49,"version_start":9,"version_start_type":9,"version_end":54,"version_end_type":51,"fixed_in":9}]
