Linux Distros Unpatched Vulnerability : CVE-2026-72234

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - batman-adv: access unicastttvn skb-data only after skb realloc The pskbmaypull called by batadvgetvid could reallocate the buffer behind the skb. Variables whic...

kernel: net: sched: UAF via missing handler for TC_ACT_CONSUMED in tcf_qevent_handle

A flaw was found in the Linux kernel's traffic control TC classifier application programming interface API. The tcfqeventhandle function does not properly handle a consumed socket buffer skb when it is processed by the defragmentation engine. This can lead to a Use-After-Free UAF vulnerability,...

RLSA-2026:54246 Moderate: kernel security update

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fixes: kernel: udf: fix partition descriptor append bookkeeping CVE-2026-45991 kernel: ice: fix double-free of txbuf skb CVE-2026-53009 For more details about the security issues, including the impact, ...

kernel: ice: fix double-free of tx_buf skb

A flaw was found in the Linux kernel's ice network driver. An error in the driver's handling of network packet transmission, specifically when icetso or icetxcsum functions fail, can lead to a double-free of a network buffer skb. This occurs because a transmit buffer txbuf may still point to an...

CVE-2026-68302

A flaw was found in the Linux kernel's Adjacency Management Protocol AMT implementation. Several AMT receive and transmit paths improperly cache pointers to socket buffer skb headers. When a helper function reallocates the skb head, these cached pointers become invalid, leading to a use-after-fre...

In the Linux kernel, the following vulnerability has been resolved: ip6vti: fix slab-use-after-free in decodesession6 When ipv6vti device is set to the qdisc of the sfb type, the cb field of the sent skb may be modified during enqueuing. Then, slab-use-after-free may occur when ipv6vti device sen...

PT-2025-3581

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.74 Description The issue occurs because the skb buffer is too small, and its actual allocation is aligned, hiding the fact that nr route frame does not validate the buffer size before using it. This can be...

CVE-2024-43881 wifi: ath12k: change DMA direction while mapping reinjected packets

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: change DMA direction while mapping reinjected packets For fragmented packets, ath12k reassembles each fragment as a normal packet and then reinjects it into HW ring. In this case, the DMA direction should be...

CVE-2024-43881

CVE-2024-43881 : In the Linux kernel, the ath12k driver used by wifi in fragmented packets reinjects fragments as normal packets. The DMA direction must be DMA_TO_DEVICE when reinjecting fragments; using DMA_FROM_DEVICE can cause an invalid payload to be reinjected and delivered to the host, enab...

CVE-2021-47224

In the Linux kernel, the following vulnerability has been resolved: net: lltemac: Make sure to free skb when it is completely used With the skb pointer piggy-backed on the TX BD, we have a simple and efficient way to free the skb buffer when the frame has been transmitted. But in order to avoid...
