Description

In the Linux kernel, the following vulnerability has been resolved: cifs: fix underflow in parse_server_interfaces() In this loop, we step through the buffer and after each item we check if the size_left is greater than the minimum size we need. However, the problem is that "bytes_left" is type ssize_t while sizeof() is type size_t. That means that because of type promotion, the comparison is done as an unsigned and if we have negative bytes left the loop continues instead of ending.

Affected configurations

• linux linux kernel (>= 4.18 < 6.1.79) • linux linux kernel (>= 6.2 < 6.6.18) • linux linux kernel (>= 6.7 < 6.7.6) • linux linux kernel 6.8
