NVD Description

Note: Versions mentioned in the description apply only to the upstream grub2-i386-pc package and not the grub2-i386-pc package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

A use-after-free vulnerability has been identified in the GNU GRUB (Grand Unified Bootloader). The flaw occurs because the file-closing process incorrectly retains a memory pointer, leaving an invalid reference to a file system structure. An attacker could exploit this vulnerability to cause grub to crash, leading to a Denial of Service. Possible data integrity or confidentiality compromise is not discarded.
