CVE-2026-74340CVE-2026-74340
Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: wcn36xx: fix OOB read from firmware count in PRINT_REG_INFO indication
The firmware-controlled rsp->count field is used as the loop bound for
indexing into the flexible rsp->regs[] array without validation against
the message length. A count exceeding the actual data causes out-of-
bounds reads from the heap-allocated message buffer.
Add a check that count fits within the received message.
