Vulnerability · CVE-2026-106464

computes the certificate signature's length as without first checking that is non-zero.

Published Oct 14, 2026 · catalog updated Oct 15, 2026 · computes the certificate signature's

Check if you run it

No confirmed exploitation is on record for CVE-2026-106464. EPSS is 0.18%. Act only if a listed version of computes the certificate signature's is installed.

Gaps on this record

  • The stored product name is a package slug. The name on this page is taken from the title (computes the certificate signature's).
  • No version range is stored. A customer cannot check an installed version against this record.
  • No vendor fix or required action is stored. Compare the linked advisory before you change production.

computes the certificate signature's length as without first checking that is non-zero. A certificate whose signature is an empty ASN.1 BIT STRING therefore parses successfully and leaves the certificate holding a signature length of and a signature pointer one byte past the end of the buffer. Certificates are parsed from the peer during the TLS handshake, so the input is remote and unauthenticated.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.

How to fix CVE-2026-106464

What to do

Three questions, each answered from this record only. Confirm the vendor advisory before you patch.

Should you patch?

No confirmed exploitation is on record for CVE-2026-106464. EPSS is 0.18%. Act only if a listed version of computes the certificate signature's is installed.

Which versions are affected?

Affected version ranges are not on this record. Compare the installed version with the linked vendor advisory before you change production.

What should an analyst verify?

CWE-125: Out-of-bounds Read; CWE-191: Integer Underflow. EPSS 0.18%. There is no CISA KEV listing. No Exploit-DB or Metasploit reference is linked. Use the source links for the original advisory.
