UBUNTU-CVE-2026-23413

In the Linux kernel, the following vulnerability has been resolved: clsact: Fix use-after-free in init/destroy rollback asymmetry Fix a use-after-free in the clsact qdisc upon init/destroy rollback asymmetry. The latter is achieved by first fully initializing a clsact instance, and then in a seco...

CVE-2026-23413

The CVE-2026-23413 entry concerns the Linux kernel: a use-after-free in the clsact qdisc during init/destroy rollback caused by asymmetrical initialization between ingress and egress sides. A failed replacement during clsact_init() (e.g., via tcf_block_get_ext()) could leave both ingress and egre...

Improper Access Control

Cilium is vulnerable to improper access control. The vulnerability is due to missing validation of non-existent or unattached AWS security group IDs in egress policies, which allows an attacker to gain broader outbound network access than intended by the policy configuration...

CVE-2026-32946

A flaw was found in Harden-Runner, a security agent for GitHub Actions runners. An attacker with existing code execution capabilities within a GitHub Actions workflow can bypass network egress policies, which are security measures designed to control outbound network connections. This bypass occu...

CVE-2026-32947

A flaw was found in Harden-Runner. A remote attacker with existing code execution within a GitHub Actions workflow could exploit a DNS over HTTPS DoH vulnerability to bypass network restrictions. This allows for the exfiltration of sensitive data by encoding it within DoH queries, which appear as...
