| Vector | AV: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 issue is related to the
ibmpex register bmc() function in the drivers/hwmon/ibmpex.c module of the Linux kernel, which is associated with the reuse of previously freed memory. This could allow an attacker to impact the confidentiality, integrity, and availability of protected information. The problem occurs when ibmpex find sensors() fails in ibmpex register bmc(), causing data to be freed but not removed from driver data.bmc data, potentially leading to a use-after-free (UAF) condition during list traversal.Recommendations
To resolve the issue, remove the
data->list from driver data.bmc data before freeing the data in the ibmpex register bmc() function.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
