Description

This security bulletin contains information about 4 vulnerabilities.


1) Protection mechanism failure (CVE-ID: CVE-2026-27140)

CWE-ID: CWE-693 - Protection Mechanism Failure

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


The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to a trust layer bypass in cmd/go when processing SWIG file names containing 'cgo' and crafted payloads at build time. A remote attacker can supply a specially crafted SWIG file to execute arbitrary code.


2) Integer overflow (CVE-ID: CVE-2026-27143)

CWE-ID: CWE-190 - Integer overflow

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


The vulnerability allows a local user to cause memory corruption.

The vulnerability exists due to integer overflow in cmd/compile when optimizing arithmetic over induction variables in loops. A local user can compile specially crafted code to cause memory corruption.

The issue can result in invalid indexing at runtime.


3) Buffer overflow (CVE-ID: CVE-2026-27144)

CWE-ID: CWE-119 - Memory corruption

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


The vulnerability allows a local user to cause memory corruption at runtime.

The vulnerability exists due to memory corruption in cmd/compile when compiling code involving a no-op interface conversion on pointers used as operands of a memory move. A local user can compile specially crafted code to cause memory corruption at runtime.


4) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-32288)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

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 memory allocation in archive/tar Reader.Next when parsing a maliciously crafted tar archive containing a large number of sparse regions encoded in the old GNU sparse map format. A remote attacker can supply a specially crafted archive to cause a denial of service.
