In the Linux kernel, the following vulnerability has been resolved:
net: qlogic/qede: fix potential out-of-bounds read in qede_tpa_cont() and qede_tpa_end()
The loops in 'qede_tpa_cont()' and 'qede_tpa_end()', iterate over 'cqe->len_list[]' using only a zero-length terminator as the stopping condition. If the terminator was missing or malformed, the loop could run past the end of the fixed-size array.
Add an explicit bound check using ARRAY_SIZE() in both loops to prevent a potential out-of-bounds access.
