Description
This PR addresses a potential buffer overflow issue in the tud_msc_read10_cb function. Previously, the function did not validate whether the combination of offset and bufsize exceeded the disk block size, which could result in out-of-bounds memory access during the memcpy operation.
Changes
Added a validation check to ensure
offset + bufsize
does not exceed the definedDISK_BLOCK_SIZE
. If this condition is violated, the function now returns -1.
