CVE-2022-41862: In PostgreSQL, a modified, unauthenticated server can send an unterminated string during the establishment of Kerberos transport encryption.
Noroxi assessment
Priority: Monitor (action score 14/100)
- 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: 0.62% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
- Fixed version: CBL Mariner 2.0 ARM 14.8-1; CBL Mariner 2.0 x64 14.8-1.
Low priority for now. Upgrade to CBL Mariner 2.0 ARM 14.8-1; CBL Mariner 2.0 x64 14.8-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
In PostgreSQL, a modified, unauthenticated server can send an unterminated string during the establishment of Kerberos transport encryption. In certain conditions a server can cause a libpq client to over-read and report an error message containing uninitialized bytes.
