In the Linux kernel, the following vulnerability has been resolved:
netfilter: ipset: Fix overflow before widen in the bitmapipcreate() function.
When firstip is 0, lastip is 0xFFFFFFFF, and netmask is 31, the value of an arithmetic expression 2 << (netmask - mask_bits - 1) is subject to overflow due to a failure casting operands to a larger data type before performing the arithmetic.
Note that it's harmless since the value will be checked at the next step.
Found by InfoTeCS on behalf of Linux Verification Center (linuxtesting.org) with SVACE.
