CVE-2026-64027

A flaw was found in the net/shaper component of the Linux kernel. A race condition exists in how VALID marks are handled for entries in an XArray. This can lead to a Use-After-Free UAF vulnerability, where memory is incorrectly freed while still in use, potentially allowing an attacker to cause a...

CVE-2026-64023

A flaw was found in the Linux kernel's GPIO General Purpose Input/Output aggregator module. This vulnerability occurs when an error condition causes memory to be prematurely freed while still being referenced in a lookup table. A local attacker could potentially exploit this timing issue, leading...

CVE-2026-64024

A flaw was found in the Linux kernel's Transmission Control Protocol TCP networking stack. This vulnerability arises from a stale per-CPU variable that can retain a previously used Initial Sequence Number ISN when certain packets are dropped. A remote attacker could exploit this by sending...

CVE-2026-64025

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter sockmap component when used with kernel TLS kTLS receive. A race condition exists where skpsockverdictdataready can improperly interact with the kTLS receive process. This can lead to a use-after-free vulnerability, potentially...

CVE-2026-64022

A flaw was found in the Linux kernel's GPIO General Purpose Input/Output aggregator component. When the aggregator device is deactivated after being configured using configfs, a dynamic software node is not properly removed. This oversight leads to a resource leak, which could potentially be...

CVE-2026-64020

A flaw was found in the Linux kernel's nvme-pci driver. This vulnerability occurs due to improper handling of peer-to-peer P2P memory, where dmavec allocations are not correctly unmapped. This oversight leads to a memory leak, which can degrade system performance and potentially lead to a denial ...

CVE-2026-64021

A flaw was found in the Linux kernel's drm/xe/oa component. A resource leak occurs in the xeoastreamopenioctl function when an execqueue reference is not properly released. This can cause the execqueue and associated file private state to remain allocated indefinitely, potentially leading to a...

CVE-2026-64016

A flaw was found in the Linux kernel's ksmbd component, which handles file sharing. When a durable network connection is re-established, an error in managing the lifetime of file objects can occur. This can lead to a situation where a file object is released from memory while still being...

CVE-2026-64015

A flaw was found in the Linux kernel's keyring code. The assocarrayfind function, used for looking up keys, was called without holding the necessary Read-Copy-Update RCU read lock. This oversight allows for a memory corruption vulnerability, particularly affecting persistent key handling, as the...

CVE-2026-64014

A flaw was found in the Linux kernel's usbtouchscreen driver. A local attacker with a specially crafted USB touch screen device could exploit this vulnerability by sending a malicious interrupt packet with an oversized length field. This improper handling of input lengths can lead to an...

CVE-2026-64012

A flaw was found in the Linux kernel's Stochastic Fair Blue SFB queue discipline net/sched: schsfb. This vulnerability occurs when the sfb component, acting as a parent queue, attempts to retrieve a network packet from its child queue using an incorrect dequeue function. This can lead to a null...

CVE-2026-64013

A flaw was found in the Linux kernel's Advanced Configuration and Power Interface ACPI button driver. This vulnerability occurs because the ACPI General Purpose Event GPE handler is not properly removed when the driver is unloaded. An attacker could potentially trigger an ACPI notify event on a...

CVE-2026-64011

A flaw was found in the Linux kernel's Near Field Communication NFC Logical Link Control Protocol LLCP component. The llcpsockrelease function, which handles the release of LLCP sockets, can incorrectly unlink a socket while it is still in a connecting state. This can result in a use-after-free...

CVE-2026-64010

A flaw was found in the Linux kernel's Near Field Communication NFC Logical Link Control Protocol LLCP connection state machine. A race condition exists where a connection acceptance packet can be processed at the same time a socket is released. This concurrency can lead to a use-after-free...

CVE-2026-64007

A flaw was found in the Linux kernel's netfilter synproxy module. When handling TCP timestamp options, a stale pointer can be used after memory reallocation. This can result in memory corruption, where data is written to a freed memory area, or lead to packets being sent with an incorrect checksu...

CVE-2026-64006

A flaw was found in the Linux kernel's Netfilter nftables component. This vulnerability occurs during lshift and rshift operations when the source and destination registers point to the same memory location. An incorrect calculation of the carry value, using the modified destination instead of th...

CVE-2026-64009

A flaw was found in the Linux kernel's xfrm IPSec framework component. A local, unprivileged user can trigger an integer underflow in the Encapsulating Security Payload ESP module's Maximum Transmission Unit MTU calculation. This underflow leads to a severe out-of-bounds write, which can cause...

CVE-2026-64005

A flaw was found in the Linux kernel's Server Message Block SMC network component. This vulnerability occurs because the system's internal tables, known as hashtables, are improperly reset after they have already been initialized and are actively in use. This incorrect re-initialization can lead ...

CVE-2026-64002

A flaw was found in the Linux kernel's IPv4 networking component. The ipv4sysctlexitnet function prematurely frees the net-ipv4.sysctllocalreservedports memory. This can lead to a use-after-free vulnerability, where other threads might attempt to access deallocated memory. Such an issue can resul...

CVE-2026-64001

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture PCM Pulse Code Modulation OSS Open Sound System component. A local user could exploit a Use-After-Free UAF vulnerability in the sndpcmossprocwrite function. This occurs when a setup entry is prematurely linked into the...
