If local_cdata->data->size 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.","published":"2026-08-15T05:54:49.022Z","modified":"2026-08-16T03:48:38.975068030Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"6.1.178"}],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-16T03:48:38.975068030Z"}}
