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

  - f2fs: split initial and dynamic conditions for extent_cache Let's allocate the extent_cache tree without     dynamic conditions to avoid a missing condition causing a panic as below. # create a file w/ a compressed     flag # disable the compression # panic while updating extent_cache F2FS-fs (dm-64): Swapfile: last extent     is not aligned to section F2FS-fs (dm-64): Swapfile (3) is not align to section: 1) creat(), 2)     ioctl(F2FS_IOC_SET_PIN_FILE), 3) fallocate(2097152 * N) Adding 124996k swap on ./swap-file.
