Linux Distros Unpatched Vulnerability : CVE-2026-23413

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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...

SUSE 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

A flaw was found in the Linux kernel's clsact qdisc. This use-after-free vulnerability occurs due to an asymmetry in the initialization and destruction rollback process. When a replacement clsact qdisc instance fails during initialization, the destroy callback is triggered without properly...

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...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the asymmetric initialization and destruction of clsact qdisc, potentially leading to reuse after...

CVE-2026-23379

CVE-2026-23379 affects the Linux kernel net/sched ETS offload path. The root cause was an overflow in WRR weight computation (q_sum, q_psum) due to using 32-bit unsigned integers, which could lead to division by zero. The documented fix is to switch q_sum and q_psum to 64-bit integers, preventing...
