Security Bulletin: IBM Watson Assistant for IBM Cloud Pak for Data is vulnerable to Linux Kernel Buffer overflow and denial of service vulnerabilities( CVE-2022-2601, CVE-2022-3775)

Summary

Potential Linux Kernel Buffer overflow and denial of service vulnerabilities( CVE-2022-2601, CVE-2022-3775) has been identified that may affect IBM Watson Assistant for IBM Cloud Pak for Data. Refer to details for additional information.

Vulnerability Details

CVEID:CVE-2022-2601
**DESCRIPTION:**Linux Kernel is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the grub_font_construct_glyph function in grub2. By using a specially-crafted pf2 font, a local authenticated attacker could overflow a buffer and execute arbitrary code or cause a denial of service condition on the system.
CVSS Base score: 8.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/242591 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H)

CVEID:CVE-2022-3775
**DESCRIPTION:**GNU grub2 is vulnerable to a denial of service, caused by an out-of-bounds write flaw when rendering certain unicode sequences in the font code. By sending a specially-crafted input, a local authenticated attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 7.1
