"The remote Fedora 37 host has a package installed that is affected by multiple vulnerabilities as referenced in the
FEDORA-2023-dfd4a6e8f2 advisory.
- An out-of-bounds memory access flaw was found in the Linux kernel's XFS file system in how a user restores
an XFS image after failure (with a dirty log journal). This flaw allows a local user to crash or
potentially escalate their privileges on the system. (CVE-2023-2124)
- A denial of service problem was found, due to a possible recursive locking scenario, resulting in a
deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-
component. (CVE-2023-2269)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
