CVE-2025-71086

CVSS v3.1

7.8

High

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The rose kill by device() function in the Linux kernel incorrectly indexes an array, potentially leading to an out-of-bounds read or an invalid socket pointer dereference. The function collects sockets into a local array and iterates to disconnect sockets bound to a device. The error occurs because the loop uses an incorrect index (cnt) instead of the correct index (i). This can result in reading uninitialized memory or accessing memory outside the array bounds, potentially leaking socket references. The vulnerable function is rose kill by device().
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
