An off-by-one vulnerability in the Linux kernel's 6lowpan multicast address compression function causes kernel stack memory leakage. The flaw overwrites a field in the compressed multicast address and fails to write part of the data array, resulting in uninitialized kernel stack data being transmitted over the network. This issue can lead to information disclosure of kernel stack contents. The vulnerability has been resolved by correcting the offsets used in the memcpy operation and zero-initializing the data array to prevent similar bugs.
