{"schema":"threatline.record/2","record":{"id":"CVE-2026-97930","aliases":[],"summary":"ALSA: usbusx2y: fix in04_last array size mismatch with in04_buf","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: usbusx2y: fix in04_last array size mismatch with in04_buf\n\nThe in04_last array in struct usx2ydev is declared as char[24], but\nin04_buf is allocated as sizeof(struct us428_ctls) which is 21 bytes.\nIn i_usx2y_in04_int(), when ctl_snapshot_last == -2 (initialization\npath):\n\n    memcpy(usx2y->in04_last, usx2y->in04_buf, sizeof(usx2y->in04_last));\n\nThis copies 24 bytes from a 21-byte slab allocation, reading 3 bytes\npast the end of the source object.\n\nIntroduce a USX2Y_IN04_SIZE constant defined as sizeof(struct\nus428_ctls) and use it consistently for the in04_last array, the\nin04_buf allocation, the URB transfer length, and the comparison loop,\nreplacing the bare 24 and 21 literals throughout.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
