If local_cdata-\u003edata-\u003esize was previously set to an\ninconsistent value, the memcpy could write past the allocated buffer.\n\nAdd a bounds check to ensure num_elems fits within the available space\nin the ipc_control_data allocation before copying.","modified":"2026-08-16T03:48:38.975068030Z","published":"2026-08-15T05:54:49.022Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72261.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1dc25a3e06364f48c4ef06016852f8b82425151a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2a591bf6fd41fd14bdae689aafac4a9ee702c23c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/390aa4c9339bb0ec0bc8d554e830faf93ca9d49e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d3abaedf6a58469610136d2dace1a85cddf7afcf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ecf67f1302f2080b4d241b973364aacda70ad740"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ee781058cd4d71e4449f41cbe6a3b8c59daa2c51"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72261.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72261"},{"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":"10f461d79c2d1afb22344986cc1b4631169cf25e"},{"fixed":"1dc25a3e06364f48c4ef06016852f8b82425151a"},{"fixed":"ee781058cd4d71e4449f41cbe6a3b8c59daa2c51"},{"fixed":"ecf67f1302f2080b4d241b973364aacda70ad740"},{"fixed":"d3abaedf6a58469610136d2dace1a85cddf7afcf"},{"fixed":"2a591bf6fd41fd14bdae689aafac4a9ee702c23c"},{"fixed":"390aa4c9339bb0ec0bc8d554e830faf93ca9d49e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72261.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.18.0"},{"fixed":"6.1.178"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.97"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72261.json"}}],"schema_version":"1.9.0"}
