A vulnerability in the Linux kernel's SMB client affects the handling of Discretionary Access Control Lists (DACLs) when the new DACL exceeds 64K in size. The issue arises due to a 16-bit accumulator wrapping when calculating the size of the DACL, causing corruption of the DACL data sent to the server. This flaw is fixed by changing the internal size accumulator to 32-bit and refusing operations that would overflow the allowed DACL size.
