{"id":"CVE-2026-46145","summary":"RDMA/mana: Validate rx_hash_key_len","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/mana: Validate rx_hash_key_len\n\nSashiko points out that rx_hash_key_len comes from a uAPI structure and is\nblindly passed to memcpy, allowing the userspace to trash kernel\nmemory. Bounds check it so the memcpy cannot overflow.","modified":"2026-06-23T15:29:18.315776370Z","published":"2026-05-28T09:36:01.805Z","related":["ALSA-2026:27353","ALSA-2026:27354","ALSA-2026:27789","openSUSE-SU-2026:10954-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46145.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/012796f9541fcd0c1fa8ae4da7eb4d83931ef838"},{"type":"WEB","url":"https://git.kernel.org/stable/c/11c1431d641e0e4e0529e96957995820600c7287"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6dd2d4ad9c8429523b1c220c5132bd551c006425"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7d7c9f0fcd19c4d2f0164347c58d49cafa961b72"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7d94f155f354b961c598f71bafa804dceded513f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46145.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46145"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0266a177631d4c6b963b5b12dd986a8c5abdbf06"},{"fixed":"7d7c9f0fcd19c4d2f0164347c58d49cafa961b72"},{"fixed":"11c1431d641e0e4e0529e96957995820600c7287"},{"fixed":"012796f9541fcd0c1fa8ae4da7eb4d83931ef838"},{"fixed":"7d94f155f354b961c598f71bafa804dceded513f"},{"fixed":"6dd2d4ad9c8429523b1c220c5132bd551c006425"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-46145.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.141"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.88"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.30"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-46145.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
