CVE-2021-46662: MariaDB through 10.5.9 allows a set_var.cc application crash via certain uses of an UPDATE statement in conjunction with a nested subquery.

MediumCVSS 5.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.39% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: galera (AlmaLinux:8) 25.3.34-4.module_el8.5.0+2632+14ced695, 25.3.34-4.module_el8.6.0+2867+72759d2f, 26.4.9-4.module_el8.6.0+2761+593e5e59; Judy (AlmaLinux:8) 1.0.5-18.module_el8.6.0+2867+72759d2f, 1.0.5-18.module_el8.5.0+2637+d11efe18, 1.0.5-18.module_el8.6.0+2761+593e5e59; mariadb (AlmaLinux:8) 3:10.5.13-1.module_el8.5.0+2637+d11efe18, 3:10.3.32-2.module_el8.5.0+2632+14ced695, 3:10.3.32-2.module_el8.6.0+2867+72759d2f.
  • Mentioned 2 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to galera (AlmaLinux:8) 25.3.34-4.module_el8.5.0+2632+14ced695, 25.3.34-4.module_el8.6.0+2867+72759d2f, 26.4.9-4.module_el8.6.0+2761+593e5e59; Judy (AlmaLinux:8) 1.0.5-18.module_el8.6.0+2867+72759d2f, 1.0.5-18.module_el8.5.0+2637+d11efe18, 1.0.5-18.module_el8.6.0+2761+593e5e59; mariadb (AlmaLinux:8) 3:10.5.13-1.module_el8.5.0+2637+d11efe18, 3:10.3.32-2.module_el8.5.0+2632+14ced695, 3:10.3.32-2.module_el8.6.0+2867+72759d2f or later.
