CVE-2026-80913 (GCVE-0-2026-80913)

Vulnerability from cvelistv5 – Published: 2026-09-04 17:19 – Updated: 2026-09-04 17:19

Title

selinux: require every boolean value to be defined

Summary

In the Linux kernel, the following vulnerability has been resolved: selinux: require every boolean value to be defined p_bools.nprim comes from the policy image independently of how many booleans follow it, and cond_index_bool() fills bool_val_to_struct[] at value - 1, so a count larger than the values present leaves NULL entries. Every user of that array then walks it by index and dereferences each entry: cond_evaluate_expr() on the access-vector path, security_get_bools() and security_get_bool_value() behind selinuxfs, and security_set_bools(). A sparse class value is absorbed by policydb_class_isvalid() and its siblings; booleans have no such predicate, and no consumer that could use one. Reject a boolean value that no boolean defines, once, where the array is built. Conforming policies define every boolean they declare and are unaffected.

GHSA-97QF-47RV-VFVF

Vulnerability from github – Published: 2026-09-04 18:31 – Updated: 2026-09-04 18:31

Details

In the Linux kernel, the following vulnerability has been resolved:

selinux: require every boolean value to be defined

p_bools.nprim comes from the policy image independently of how many booleans follow it, and cond_index_bool() fills bool_val_to_struct[] at value - 1, so a count larger than the values present leaves NULL entries. Every user of that array then walks it by index and dereferences each entry: cond_evaluate_expr() on the access-vector path, security_get_bools() and security_get_bool_value() behind selinuxfs, and security_set_bools(). A sparse class value is absorbed by policydb_class_isvalid() and its siblings; booleans have no such predicate, and no consumer that could use one.

Reject a boolean value that no boolean defines, once, where the array is built. Conforming policies define every boolean they declare and are unaffected.

  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nselinux: require every boolean value to be defined\n\np_bools.nprim comes from the policy image independently of how many\nbooleans follow it, and cond_index_bool() fills bool_val_to_struct[] at\nvalue - 1, so a count larger than the values present leaves NULL entries.\nEvery user of that array then walks it by index and dereferences each\nentry: cond_evaluate_expr() on the access-vector path,\nsecurity_get_bools() and security_get_bool_value() behind selinuxfs, and\nsecurity_set_bools(). A sparse class value is absorbed by\npolicydb_class_isvalid() and its siblings; booleans have no such\npredicate, and no consumer that could use one.\n\nReject a boolean value that no boolean defines, once, where the array is\nbuilt. Conforming policies define every boolean they declare and are\nunaffected.",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
