CVE-2026-64289

A flaw was found in the Linux kernel. In the iommufd component, the iommufdhwptinvalidate function allows a local user to provide excessively large values for entrynum and entrylen during cache invalidation. This can lead to a Denial of Service DoS by causing the system to become unresponsive...

CVE-2026-64469

A flaw was found in the Linux kernel's binder component. This vulnerability allows a local attacker to trigger a use-after-free error due to a race condition during specific thread and process operations. Successful exploitation could lead to arbitrary code execution, granting the attacker...

CVE-2026-64327

A flaw was found in the Linux kernel's FunctionFS ffs module, which handles USB gadget functionality. This vulnerability occurs because the endpoint direction epfile-in was not correctly initialized until a USB host connected. Consequently, early operations initiated by userspace programs could...

CVE-2026-64407

A flaw was found in the Linux kernel's Bluetooth driver. A malicious Bluetooth controller could send a specially crafted firmware download request that causes an out-of-bounds read. This allows the driver to read memory beyond the intended firmware data and send it back over the Universal...

CVE-2026-64333

A flaw was found in the Linux kernel's digiacceleport USB serial driver. This vulnerability allows a local attacker with access to the affected USB serial device to corrupt the write buffer due to improper handling of write operations and timeouts. This could lead to arbitrary code execution,...

CVE-2026-64258

A flaw was found in the fuse-uring component of the Linux kernel. When a copy operation to the userspace ring buffer fails, a request can be terminated improperly, leading to a NULL pointer dereference. This vulnerability could allow a local attacker to cause a system crash, resulting in a Denial...

CVE-2026-64504

A flaw was found in the Linux kernel's bmc150 accelerometer driver. A malicious or malfunctioning accelerometer device, or an attacker tampering with the I2C/SPI bus, can report an excessively large number of FIFO frames. This improper handling of the frame count leads to a stack out-of-bounds...

CVE-2026-64510

A flaw was found in the Linux kernel's Advanced Configuration and Power Interface ACPI Non-Volatile Memory NVM Firmware Interface Table NFIT core. Improper error handling during the initialization process can leave a dangling pointer. A local attacker could potentially trigger an ACPI Machine Che...

CVE-2026-64426

A flaw was found in the Linux kernel's iouring/nop component. A local user could exploit this by submitting a specially crafted no-operation NOP request. This could lead to a file reference not being properly released, resulting in a memory leak. Over time, this memory leak could impact system...

CVE-2026-64381

A flaw was found in the SMB client of the Linux kernel. A remote attacker could exploit a memory leak in the receiveencryptedstandard function by sending specially crafted compound Protocol Data Units PDUs. This vulnerability occurs because a buffer is allocated before a necessary size check,...

kernel: xfrm: defensively unhash xfrm_state lists in __xfrm_state_delete

A flaw was found in the Linux kernel's xfrm IPSec framework subsystem. This vulnerability, a use-after-free, occurs when the system incorrectly manages memory related to security policies, specifically during the deletion of xfrmstate lists. An attacker with local access could exploit this flaw b...

kernel: net: sched: act_csum: validate nested VLAN headers

A flaw was found in the Linux kernel's network scheduler component. A remote attacker could send specially crafted network packets containing nested Virtual Local Area Network VLAN headers. This could cause the kernel to read beyond allocated memory, leading to a system crash and a denial of...

kernel: nvmet-tcp: fix race between ICReq handling and queue teardown

A flaw was found in the Linux kernel's NVMe over TCP nvmet-tcp implementation. A race condition exists between the handling of an Initialization Connection Request ICReq and the teardown of a queue. A remote attacker, by sending an ICReq and immediately closing the connection, could trigger a...

kernel: xfrm: defensively unhash xfrm_state lists in __xfrm_state_delete

A flaw was found in the Linux kernel's xfrm IPSec framework subsystem. This vulnerability, a use-after-free, occurs when the system incorrectly manages memory related to security policies, specifically during the deletion of xfrmstate lists. An attacker with local access could exploit this flaw b...

kernel: netfilter: nf_conntrack_helper: pass helper to expect cleanup

A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nfconntrackhelper. When a connection tracking helper is unregistered, its associated expectations are not properly cleaned up. This oversight can lead to a use-after-free vulnerability, where the system attempts t...

kernel: net: sched: act_csum: validate nested VLAN headers

A flaw was found in the Linux kernel's network scheduler component. A remote attacker could send specially crafted network packets containing nested Virtual Local Area Network VLAN headers. This could cause the kernel to read beyond allocated memory, leading to a system crash and a denial of...

kernel: ALSA: usb-audio: Add sanity check for OOB writes at silencing

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture USB audio subsystem. An inconsistency in how USB audio playback and capture streams are handled can lead to an out-of-bounds write to a memory buffer. This can result in a system crash, causing a denial of service for a...

CVE-2026-64527

A flaw was found in the drm/hyperv component of the Linux kernel. The hypervreceivesub function, responsible for processing VMBus packets, does not adequately validate the size of incoming data. This oversight allows a malicious or compromised host to send specially crafted packets, potentially...

CVE-2026-64455

A flaw was found in the Linux kernel's chaoskey driver. A local user could trigger a use-after-free vulnerability by closing the device file after the associated USB device has been unplugged. This could lead to a system crash due to memory corruption when a debugging statement attempts to access...

CVE-2026-64408

A flaw was found in the Bluetooth Network Encapsulation Protocol BNEP module of the Linux kernel. The bnepaddconnection function reads the Logical Link Control and Adaptation Protocol L2CAP connection without properly holding a channel lock. This can allow a local attacker to trigger a...
