Since we're inside mmap, we cannot safely use\nthe io_uring lock. Rely on the fact that we can lookup the buffer list\nunder RCU now and grab a reference to it, preventing it from being\nunregistered until we're done with it. The lookup returns the\nio_buffer_list directly with it referenced.","affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"09f7520048eaaee9709091cd2787966f807da7c5"},{"fixed":"65938e81df2197203bda4b9a0c477e7987218d66"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5cf4f52e6d8aa2d3b7728f568abbf9d42a3af252"},{"fixed":"5fd8e2359498043e0b5329a05f02d10a9eb91eb9"},{"fixed":"561e4f9451d65fc2f7eef564e0064373e3019793"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.6.5"},{"fixed":"6.6.26"}]}],"versions":["v6.6.25","v6.6.24","v6.6.23","v6.6.22","v6.6.21","v6.6.20","v6.6.19","v6.6.18","v6.6.17","v6.6.16","v6.6.15","v6.6.14","v6.6.13","v6.6.12","v6.6.11","v6.6.10","v6.6.9","v6.6.8","v6.6.7","v6.6.6","v6.6.5"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-35880.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.26"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.8.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-35880.json"}}],"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/561e4f9451d65fc2f7eef564e0064373e3019793"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5fd8e2359498043e0b5329a05f02d10a9eb91eb9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/65938e81df2197203bda4b9a0c477e7987218d66"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/35xxx/CVE-2024-35880.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-35880"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/35xxx/CVE-2024-35880.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
