CVSS v3.1

3.3

Baixa

VetorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.17.4
Description The issue is related to an integer overflow in the alarm timer nsleep function due to a large relative timeout. This overflow occurs because ktime add safe is not used, which can lead to a denial of service.
Recommendations For Linux kernel versions prior to 4.17.4, update to version 4.17.4 or later to resolve the issue. As a temporary workaround, consider restricting the use of the alarm timer nsleep function to minimize the risk of exploitation.
