CVE-2024-27027

CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The issue arises when there are multiple registrations of the same pin on the same dpll device, resulting in warnings. The problem is that in both dpll xa ref dpll del() and dpll xa ref pin del() functions, registration is only removed from the list when the reference count drops to zero, which is incorrect. The registration should be removed always. To fix this, the registration should be removed from the list and freed unconditionally.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
