Doc Text:
A vulnerability was found in the Linux kernel's netlink component, caused by missing size validations for big-endian integer types NLA_BE16 and NLA_BE32. A lack of proper checks means that if a malformed or too-small attribute is passed, it can lead to an out-of-bounds read, potentially causing system instability.
