EUVD-2026-103882

In the Linux kernel, the following vulnerability has been resolved: net: cap skb-queuemapping when the tx queue is picked skbedit can set skb-queuemapping and raise the per-CPU skiptxqueue flag so devqueuexmit honours the mapping. devqueuexmit cleared the flag before schhandleegress and only read...

CVE-2026-98797

The Linux kernel is vulnerable to a slab-out-of-bounds error in taprio_enqueue() caused by a stale skb->queue_mapping value. When using skbedit, a nested transmit (such as a mirror or redirect) could set the skip_txqueue flag, which the outer transmit might incorrectly consume. If a forwarded ...

CVE-2026-43238

A flaw was found in the Linux kernel. A divide-by-zero vulnerability exists in the tcfskbedithash function within the networking scheduler component. This occurs when calculating the mappingmod value, where a large range wraps to zero, leading to a division by zero error. This flaw can cause a...

CVE-2026-43238

CVE-2026-43238 is a Linux kernel issue in the net/sched act_skbedit module. The bug arises in tcf_skbedit_hash() when calculating mapping_mod = queue_mapping_max - queue_mapping + 1, which could reach 65536 for full u16 queue ranges. This value cannot fit in a u16 and previously wrapped to 0, cau...

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 an overflow in the range size calculation in the tcfskbedithash function. This vulnerability may...

PT-2026-37578

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A divide-by-zero flaw exists in the tcf skbedit hash function.
