Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
bnxt_en: Mask the bd_cnt field in the TX BD properly<br />
<br />
The bd_cnt field in the TX BD specifies the total number of BDs for<br />
the TX packet. The bd_cnt field has 5 bits and the maximum number<br />
supported is 32 with the value 0.<br />
<br />
CONFIG_MAX_SKB_FRAGS can be modified and the total number of SKB<br />
fragments can approach or exceed the maximum supported by the chip.<br />
Add a macro to properly mask the bd_cnt field so that the value 32<br />
will be properly masked and set to 0 in the bd_cnd field.<br />
<br />
Without this patch, the out-of-range bd_cnt value will corrupt the<br />
TX BD and may cause TX timeout.<br />
<br />
The next patch will check for values exceeding 32.
