Vulnerability Details : CVE-2024-26668
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_limit: reject configurations that cause integer overflow
Reject bogus configs where internal token counter wraps around.
This only occurs with very very large requests, such as 17gbyte/s.
Its better to reject this rather than having incorrect ratelimit.

CWE ids for CVE-2024-26668
-
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.Assigned by: nvd@nist.gov (Primary)
