CVE-2026-64556 perf/core: Detach event groups during remove_on_exec

In the Linux kernel, the following vulnerability has been resolved: perf/core: Detach event groups during removeonexec perfeventremoveonexec removes events by calling perfeventexitevent. For top-level events, this removes the event from the context with DETACHEXIT only. This can leave inconsisten...

CVE-2026-64556

CVE-2026-64556 pertains to the Linux kernel PMU subsystem (perf/core). When a performance event group leader is removed during process exit, its surviving siblings can remain active and still linked to the removed leader’s list, leaving the PMU context active list in a potentially inconsistent st...

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,...

An update for kernel is now available for Red Hat Enterprise Linux 10.0 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for...

CVE-2026-64520

A flaw was found in the Linux kernel's ARM Firmware Framework for ARM FFA. The PARTITIONINFOGETREGS function, which handles copying partition descriptors, did not adequately validate the indices provided by the firmware. This oversight could allow the system to process inconsistent data, resultin...

CVE-2026-64439

A flaw was found in the Linux kernel's Kerberos 5 krb5 cryptography module. This use-after-free vulnerability occurs when an asynchronous Authenticated Encryption with Associated Data AEAD instance is used. The system prematurely frees a memory buffer while a backend process still holds a pointer...

USN-8620-2: Linux kernel (Azure FIPS) vulnerabilities

Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could expose...

USN-8620-2 linux-azure-fips vulnerabilities

Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could expose...

CVE-2026-64259

A flaw was found in the Linux kernel's fuse-uring component. A local attacker could exploit a race condition by sending specially crafted requests before they are fully processed. This could lead to a use-after-free vulnerability, potentially allowing for arbitrary code execution or denial of...

CVE-2026-64516

A flaw was found in the Linux kernel's drm/amdgpu/vce1 component. The vulnerability arises from incorrect calculations of the VCE 1 firmware size and offsets, which could lead to an out-of-bounds access. This issue could potentially allow a local attacker to cause system instability or a denial o...

CVE-2026-64401

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability, a use-after-free, occurs when handling witness registrations. Specifically, a second mount for the same network share can cause the system to incorrectly reference a previously freed connection, leading to...

CVE-2026-64322

A flaw was found in the Linux kernel's Universal Disk Format UDF filesystem. The udfloadsparablemap function incorrectly validates the length of the sparing table, treating it as a byte count instead of an entry count. This allows a local attacker, by providing a specially crafted UDF image, to...

CVE-2026-64474

A flaw was found in the Linux kernel's Virtual Function I/O VFIO device migration feature. The vfiomiggetnextstate function, responsible for managing device migration states, contains an infinite loop. This occurs when processing certain blocked transitions, causing the system to hold a driver...

CVE-2026-64421

A flaw was found in the Linux kernel's imx8-isi media driver. This use-after-free vulnerability occurs during the removal of the driver due to an incorrect order of cleanup operations. A local attacker could potentially exploit this to cause a denial of service or achieve arbitrary code execution...

CVE-2026-64499

A flaw was found in the Linux kernel's ti-ads1119 Analog-to-Digital Converter ADC driver. This vulnerability occurs during the buffer pre-enable process, where a Power Management PM reference is not properly released if an I2C communication error occurs. This oversight can lead to a resource leak...

CVE-2026-64366

A flaw was found in the Linux kernel's Wacom Human Interface Device HID driver. This vulnerability occurs in the wacomwacqueueinsert function when handling incoming reports. Improper management of the kernel's internal buffer kfifo can lead to a slab-out-of-bounds write, allowing an attacker to...

CVE-2026-64440

A flaw was found in the Linux kernel's rtl8723bs Wi-Fi driver. A remote attacker, by operating a malicious Access Point AP, can send a specially crafted 802.11 AssocResponse frame. This can trigger an out-of-bounds write vulnerability in the HTcapshandler function, leading to memory corruption...

CVE-2026-64534

A flaw was found in the Linux kernel's NVMe over TCP nvmet-tcp implementation. When a data digest mismatch occurs, a reference count underflow can happen due to an unconditional cleanup call. This issue can lead to a use-after-free condition and ultimately result in a permanent workqueue deadlock...

CVE-2026-64533

A flaw was found in the Linux kernel's ntfs3 filesystem driver. A local attacker could exploit this vulnerability by crafting a specially designed NTFS filesystem image.
