🚨 CVE-2026-43503 — DirtyClone When Shared Memory Stops Being Shared Safely. A Local Privilege Escalation vulnerability caused by improper propagation of the SKBFLSHAREDFRAG flag inside the Linux networking stack. 📖 Overview CVE-2026-43503 , nicknamed DirtyClone , is a High Severity Local Privileg...
CVE-2026-64563_EXP
CVE-2026-64563EXP For experimental research only. The code for prefetch and nperm the memory reference set.gdb needs to be configured is not attached, and since it has not been optimized, the hit probability is low. The author noticed that the vulnerability author has already released relevant...
SUSE CVE-2026-98968
In the Linux kernel, the following vulnerability has been resolved: amt: send the relay's General Query directly from the receive path An skb queued in a qdisc can outlive the tunnel it references through a raw pointer in skb-cb. For example, with igmpqrv set to 1 on the relay a tunnel lives for...
SUSE CVE-2026-99027
In the Linux kernel, the following vulnerability has been resolved: net: team: stop reusing skb after queue override A nonzero devqueuexmit result does not return ownership of the skb. When an override port's qdisc drops it, the queue override helper used to try another port or the mode transmit ...

CVE-2026-99027
The Linux kernel contains a slab-use-after-free vulnerability within the net: team component. The issue occurs because a nonzero dev_queue_xmit() result does not return ownership of the skb . Consequently, when an override port's qdisc drops the packet, the queue override helper incorrectly attem...

CVE-2026-99026
In the Linux kernel, the following vulnerability has been resolved: net: team: free skb when broadcast has no txable port bctransmit sends the original skb through the last txable port. When no port is txable, it returns false without consuming the skb, but teamxmit still returns NETDEVTXOK...
CVE-2026-99014
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: Fix command skb lifetime during scan setup During PA sync scan setup, hcilesetextscanparamsync gets the address used for the PALINK lookup from hcisentcmddata. The returned pointer borrows storage from sentcmd...
CVE-2026-99010
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: free the skb when the DLC has no owner rfcommrecvdata hands the skb to d-dataready and returns 0 without freeing it, so the callback owns the skb from that point on. The tty implementation frees it when the DLC...

CVE-2026-98968
The Linux kernel contains a use-after-free vulnerability in the amt driver. A socket buffer (skb) queued in a qdisc can outlive the tunnel it references because the tunnel pointer is stored as a raw pointer in skb->cb. Specifically, if a tunnel expires and is freed while a packet (e.g., one wi...
