What the advisory describes
In the Linux kernel, the following vulnerability has been resolved: ALSA: usbusx2y: fix in04_last array size mismatch with in04_buf The in04_last array in struct usx2ydev is declared as char[24], but in04_buf is allocated as sizeof(struct us428_ctls) which is 21 bytes. In i_usx2y_in04_int(), when ctl_snapshot_last == -2 (initialization path): memcpy(usx2y->in04_last, usx2y->in04_buf, sizeof(usx2y->in04_last)); This copies 24 bytes from a 21-byte slab allocation, reading 3 bytes past the end of the source object. Introduce a USX2Y_IN04_SIZE constant defined as sizeof(struct us428_ctls) and use it consistently for the in04_last array, the in04_buf allocation, the URB transfer length, and the comparison loop, replacing the bare 24 and 21 literals throughout.
