| Vetor | AV:N/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 4.20.5
Description
The issue is related to a use-after-free vulnerability in the IPMI driver interface (drivers/char/ipmi/ipmi msghandler.c code) of the Linux kernel. This vulnerability can be exploited by arranging for certain simultaneous execution of the code, as demonstrated by a "service ipmievd restart" loop, potentially leading to a denial of service. The exploitation of this vulnerability may allow a remote attacker to cause a service disruption using the IPMI interface.
Recommendations
For Linux kernel versions prior to 4.20.5, update to version 4.20.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the IPMI interface to minimize the risk of exploitation. Avoid using the
ipmi msghandler.c code in the affected kernel versions until the issue is resolved.Correção
