Описание
In the Linux kernel, the following vulnerability has been resolved:
lib/generic-radix-tree.c: Don't overflow in peek()
When we started spreading new inode numbers throughout most of the 64
bit inode space, that triggered some corner case bugs, in particular
some integer overflows related to the radix tree code. Oops.
A flaw was found in the Linux kernel's generic radix tree implementation. An integer overflow occurs when iterating over a radix tree with large values, such as wide-range file identifiers, due to missing boundary checks during iterator progression. A local authenticated user could trigger this vulnerability to cause a Denial of Service (DoS) by crashing the system.
Отчет
This vulnerability is evaluated with a Low severity rating for Red Hat Enterprise Linux because successful exploitation demands local authenticated access and edge-case traversals across exceptionally wide 64-bit identifier ranges. In typical enterprise environments, unprivileged users have limited influence over the internal radix tree lookups that trigger this boundary condition. The potential impact is strictly confined to a system crash, with no risk to data integrity or confidentiality.
