Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> RDMA/bnxt_re: wraparound mbox producer index<br /> <br /> Driver is not handling the wraparound of the mbox producer index correctly.<br /> Currently the wraparound happens once u32 max is reached.<br /> <br /> Bit 31 of the producer index register is special and should be set<br /> only once for the first command. Because the producer index overflow<br /> setting bit31 after a long time, FW goes to initialization sequence<br /> and this causes FW hang.<br /> <br /> Fix is to wraparound the mbox producer index once it reaches u16 max.
