CVE-2024-26849

Name of the Vulnerable Software and Affected Versions 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.
