{"id":"CVE-2026-68348","summary":"ASoC: tas2781: bound firmware description string parsing","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nASoC: tas2781: bound firmware description string parsing\n\nThe TAS2781 firmware parser reads several variable-length description\nstrings with strlen() before checking that the string terminator is\npresent inside the firmware blob. A malformed firmware image without a\nNUL terminator can therefore make the parser walk past the end of the\nfirmware buffer before the later size checks run.\n\nAdd a small bounded string-length helper and use it for all description\nfields that are parsed from the firmware buffer. Keep the existing size\nchecks for the fixed bytes that follow each string.","modified":"2026-08-12T04:19:22.752097438Z","published":"2026-08-10T12:03:25.193Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68348.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0ec45e80a82785ee147516fdecf5c93707dec119"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3ddb0d3e36507615e5ef010a879357a54870adf5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/41ae2b7d37c3dd82302167496836cca9f0328374"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bc889dfcea9294a1eae7f8e2f3573a90764ae4d0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e75ef37d83c90b09bedb601624b47e168202b226"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68348.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68348"},{"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":"915f5eadebd29ba185ac506766a90120153b7e14"},{"fixed":"3ddb0d3e36507615e5ef010a879357a54870adf5"},{"fixed":"0ec45e80a82785ee147516fdecf5c93707dec119"},{"fixed":"41ae2b7d37c3dd82302167496836cca9f0328374"},{"fixed":"e75ef37d83c90b09bedb601624b47e168202b226"},{"fixed":"bc889dfcea9294a1eae7f8e2f3573a90764ae4d0"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68348.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.5.0"},{"fixed":"6.6.148"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68348.json"}}],"schema_version":"1.9.0"}
