Description

This security bulletin contains information about 3 vulnerabilities.


1) Time-of-check Time-of-use (TOCTOU) Race Condition (CVE-ID: CVE-2026-32282)

CWE-ID: CWE-367 - Time-of-check Time-of-use (TOCTOU) Race Condition

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to modify file permissions outside the intended root directory.

The vulnerability exists due to improper access control in Root.Chmod and internal/syscall/unix Fchmodat when handling a chmod operation on Linux. A local user can replace the target with a symlink during the check-and-operation window to modify file permissions outside the intended root directory.

Exploitation requires a race condition in which the target is swapped with a symlink while the chmod operation is in progress.


2) Dependency on vulnerable third-party component (CVE-ID: CVE-2026-32283)

CWE-ID: CWE-1395 - Dependency on Vulnerable Third-Party Component

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to dependency on a vulnerable third-party component in the Go standard library used by Fleet Server when handling network input. A remote attacker can send a specially crafted payload to cause a denial of service.

All configurations are affected.


3) Resource exhaustion (CVE-ID: CVE-2026-32280)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in the Certificate.Verify chain-building logic in crypto/x509 when processing a large number of intermediate certificates supplied through VerifyOptions.Intermediates. A remote attacker can provide a large number of intermediate certificates to cause a denial of service.

This affects both direct users of crypto/x509 and users of crypto/tls.
