{"id":"CVE-2026-72302","summary":"ASoC: SOF: ipc3-control: Use overflow checks in control_update size calc","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nASoC: SOF: ipc3-control: Use overflow checks in control_update size calc\n\nIn sof_ipc3_control_update(), the expected_size calculation uses\nfirmware-provided cdata-\u003enum_elems in arithmetic that could overflow\non 32-bit platforms, wrapping to a small value. This would allow the\ncdata-\u003erhdr.hdr.size comparison to pass with mismatched sizes,\npotentially leading to out-of-bounds access in snd_sof_update_control.\n\nUse check_mul_overflow() and check_add_overflow() to detect and reject\noverflowed size calculations.","modified":"2026-08-16T03:48:53.833895883Z","published":"2026-08-15T05:55:21.049Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72302.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/312c7d2ebe696da3f885eee77d52297664e57c53"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6856b3c23b0995eefad5a6142b4365ef70e1fe4a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/711d912b18763af62a63aa8f2419a774eb63bba4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8791977d7289f6e9d2b014f60a5455f053a7bc04"},{"type":"WEB","url":"https://git.kernel.org/stable/c/89a2309a9eec80d4c19e3aed62c4f923594d1911"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ffd79e77f2fbacd7a5d40ad1d4c7f3f089a8f2f3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72302.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72302"},{"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":"6856b3c23b0995eefad5a6142b4365ef70e1fe4a"},{"fixed":"89a2309a9eec80d4c19e3aed62c4f923594d1911"},{"fixed":"ffd79e77f2fbacd7a5d40ad1d4c7f3f089a8f2f3"},{"fixed":"711d912b18763af62a63aa8f2419a774eb63bba4"},{"fixed":"312c7d2ebe696da3f885eee77d52297664e57c53"},{"fixed":"8791977d7289f6e9d2b014f60a5455f053a7bc04"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72302.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-2026-72302.json"}}],"schema_version":"1.9.0"}
