CVE-2024-26828
MEDIUMLinux Kernel 4.18-6.1.78, 6.2-6.6.17, 6.7-6.7.5 - Integer Underflow in CIFS Server Interface Parser
Title source: llmDescription
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.
