CVE-2026-98534: ipe: fix use-after-free when auditing a newly loaded policy

Noroxi assessment

Priority: Monitor (action score 0/100)

  • 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: 0.20% (FIRST EPSS).
  • Fixed version: Linux Linux 48f7d0233c3cc8d986d1177d0e5dd4af435e7265, 9814077275eca36ebf8d510d2f076d235ff9f51a, b72d6c72b4bfbc021e8e127fa13e0f27d09be737.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 48f7d0233c3cc8d986d1177d0e5dd4af435e7265, 9814077275eca36ebf8d510d2f076d235ff9f51a, b72d6c72b4bfbc021e8e127fa13e0f27d09be737 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: ipe: fix use-after-free when auditing a newly loaded policy new_policy() audits the policy after ipe_new_policyfs_node() publishes it and drops the new directory's inode lock. A concurrent delete can free the policy while ipe_audit_policy_load() is still using it. Audit the successful load under that lock. [FW: remove model name according to latest guideline]

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
