medium Nessus Plugin ID 223236

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- The __mptctl_ioctl function in drivers/message/fusion/mptctl.c in the Linux kernel before 5.4.14 allows local users to hold an incorrect lock during the ioctl operation and trigger a race condition, i.e., a double fetch vulnerability, aka CID-28d76df18f0a. NOTE: the vendor states The security impact of this bug is not as bad as it could have been because these operations are all privileged and root already has enormous destructive power. (CVE-2020-12652)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
