- grub2: Buffer overflow in grub_font_construct_glyph() can lead to out-of-bound write and possible secure boot bypass (CVE-2022-2601)
- grub2: Heap based out-of-bounds write when redering certain unicode sequences (CVE-2022-3775)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
