In the Linux kernel, the following vulnerability has been resolved: netfilter: ebtables: module names must be null-terminated We need to explicitly check the length, else we may pass non-null terminated string to request_module().

A flaw was found in the Linux kernel's netfilter ebtables component. A local attacker could exploit this vulnerability by providing a specially crafted module name that is not properly null-terminated. This improper string handling could lead to a buffer over-read when the `request_module()` function processes the string. Successful exploitation could result in information disclosure, allowing an attacker to read sensitive kernel memory, or a denial of service (DoS), causing the system to crash.
