Linux kernel (affected versions not specified)
Description
The issue is related to the netlink component of the Linux kernel, where the validation code reads past a malformed attribute due to a missing size in the minlen array for NLA BE32. This can lead to an uninit-value bug, potentially causing a denial of service. The vulnerability is associated with the
nla validate range unsigned, nla validate int range, and validate nla functions in lib/nlattr.c. Other attributes like BITFIELD32, SINT, and UINT are also missing from the minlen array and should be added.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
