Siebe Devroe, Héloïse Gollier, and Mathy Vanhoef discovered that the WiFi implementation in the Linux kernel did not properly handle aggregated frames in mesh networks, due to an incorrect fix for CVE-2020-24588. A physically proximate attacker could use this issue to inject packets. CVE-2025-275...

USN-8629-2: Linux kernel (AWS) vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - x86 architecture; - InfiniBand drivers; - Network drivers; - Network traffic control; - IPv4 networking; - IPv6...

kernel: netfilter: flowtable: strictly check for maximum number of actions

A flaw was found in the Netfilter flowtable component of the Linux kernel. This vulnerability occurs because the system does not strictly check the maximum number of hardware offload actions for IPv6, allowing it to process more actions than supported. This could potentially lead to system...

kernel: netfilter: nft_inner: Fix IPv6 inner_thoff desync

A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nftinner module. This vulnerability arises from an incorrect handling of IPv6 inner packet processing, where the transport header offset innerthoff becomes desynchronized from the Layer 4 protocol l4proto. A remot...

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,...

kernel: dlm: validate length in dlm_search_rsb_tree

A flaw was found in the Linux kernel's Distributed Lock Manager dlm module. An attacker could send specially crafted network messages with an oversized length parameter to the dlmdumprsbname function. This lack of validation can lead to an out-of-bounds write in the dlmsearchrsbtree function,...

kernel: ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()

A flaw was found in the Linux kernel's IPv6 ICMP error generation. A remote attacker could send a specially crafted IPv4 ICMP error packet with a Common Internet Protocol Security Option CIPSO IP option. This could lead to incorrect handling of packet control block data when generating an IPv6 IC...

CVE-2026-72486

A flaw was found in the Linux kernel's mtk-adsp mailbox driver. During device teardown, if the Sound Open Firmware SOF audio driver fails to initialize, a timing issue can occur where an interrupt is processed after the associated memory has been released. This Use-After-Free UAF vulnerability ca...

CVE-2026-72483

A flaw was found in the Linux kernel's USB host driver, specifically in the max3421hubcontrol function. A malicious userspace task with access to the root hub can trigger a shift-out-of-bounds vulnerability by issuing a crafted USBDEVFSCONTROL ioctl. This can lead to arbitrary bit corruption of t...

CVE-2026-72472

A flaw was found in the Network File System NFS component of the Linux kernel. Inadequate synchronization during the traversal of the file lock list can lead to a use-after-free UAF vulnerability. This occurs when certain functions release file locks prematurely while iterating, potentially...

CVE-2026-72361

A flaw was found in the Linux kernel's drm/xe/hwengine component. An error handling path in the hwengineinit function attempts to free a Buffer Object BO that is already managed by the device resource management devm system. This redundant free operation results in a double-free vulnerability. A...

CVE-2026-72303

A flaw was found in the ASoC Sound Open Firmware SOF ipc4-control component of the Linux kernel. This vulnerability arises from insufficient validation of the MODULENOTIFICATION payload length when handling control updates. An attacker could potentially exploit this by providing a malformed...

CVE-2026-72247

A flaw was found in the Linux kernel's netfilter nfconncount component. An incorrect comparison of conntrack zones in the connection counting logic can cause different zones to be treated as equal. This miscalculation in connection deduplication may lead to connection limits not being properly...

CVE-2026-72163

A flaw was found in the Linux kernel's OCFS2 component. A local user with write access to an OCFS2 filesystem could trigger a kernel panic by performing a direct write over unwritten extents. This occurs when the journal aborts during Direct I/O DIO completion, leading to a NULL pointer dereferen...

CVE-2026-72018

A flaw was found in the Linux kernel's dibs: loopback functionality. A missing bounds check in the movedata function allows an attacker to provide an out-of-bounds offset or an oversized write. This can lead to an out-of-bounds write past an allocated kernel buffer, potentially causing memory...

CVE-2026-72017

A flaw was found in the Linux kernel's MACB network driver. This driver fails to properly release outgoing Socket Kernel Buffers SKBs when the driver is closed. This continuous leakage of resources can lead to resource exhaustion over time, potentially resulting in a Denial of Service DoS conditi...

CVE-2026-72016

A flaw was found in the Linux kernel's CPU hotplug mechanism on arm64 systems. When a system is booted with more maximum CPUs configured than are physically present, some CPUs are incorrectly marked as present but are not fully registered. This can lead to a kernel warning due to a null kobject...

CVE-2026-72015

A flaw was found in the Linux kernel's fs/resctrl component. A double-free vulnerability occurs when a pseudo-locked group's Resource Monitoring ID RMID is freed upon creation and then again during unmount operations by the rmdirallsub function. This double-free can lead to memory corruption,...

CVE-2026-72014

A flaw was found in DRBD, a component of the Linux kernel. A malicious or man-in-the-middle DRBD peer can send a specially crafted data reply with an out-of-range payload size. This incorrect size calculation can lead to an out-of-bounds write, allowing the attacker to copy arbitrary data past a...
