CVE-2026-64557

A flaw was found in the Linux kernel's Bluetooth L2CAP component. A race condition exists during the handling of new Bluetooth connections, where a newly created socket can be prematurely freed by another process before a callback function completes its operation. This use-after-free vulnerabilit...

CVE-2026-64303

A flaw was found in the Linux kernel's fsl-lpspi driver. This vulnerability occurs when the transmit TX Direct Memory Access DMA channel fails to prepare, but the receive RX DMA channel continues to operate. This can lead to memory corruption or a use-after-free condition, potentially allowing an...

CVE-2026-64311

A flaw was found in the Linux kernel's loongson-rng random number generator. This component suffered from a use-after-free vulnerability, which could lead to system instability or denial of service. Additionally, the loongson-rng did not provide forward security, a crucial cryptographic property...

CVE-2026-64345

A flaw was found in the Linux kernel's USB printer gadget driver. The printeropen function incorrectly increments a reference counter even when the device is already in use and the open operation fails. This prevents the reference from being properly released, leading to a permanent leak of syste...

CVE-2026-64556

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-2026-64557

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: Fix use-after-free in l2capsocknewconnectioncb l2capsocknewconnectioncb returned l2cappisk-chan after releasesockparent. Once the parent lock is dropped the newly enqueued child socket sk is reachable via the...

UBUNTU-CVE-2026-64557

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: Fix use-after-free in l2capsocknewconnectioncb l2capsocknewconnectioncb returned l2cappisk-chan after releasesockparent. Once the parent lock is dropped the newly enqueued child socket sk is reachable via the...

CVE-2026-64324

A flaw was found in the Linux kernel's Universal Disk Format UDF filesystem. The udffreeblocks function fails to properly validate free block extents against the partition length. This allows a local, unprivileged user to create a specially crafted UDF filesystem that, when a file on it is...

CVE-2026-64271

A flaw was found in the Linux kernel's touchwin input driver. A malicious, malfunctioning, or counterfeit Touchwindow peripheral can exploit an unbounded heap out-of-bounds write vulnerability by streaming specific non-zero bytes. This prevents the packet index from resetting, allowing the...

CVE-2026-64292

A flaw was found in the Linux kernel's iommufd component. A local user can exploit this vulnerability by allocating large veventq queues, which are processed inside a spinlock. This can lead to the exhaustion of atomic memory reserves, resulting in a Denial of Service DoS condition...

CVE-2026-64299

A flaw was found in the Linux kernel's tracing subsystem. This vulnerability allows a local attacker to trigger an out-of-bounds read by providing specially crafted input to glob matching functions. The issue arises because these functions did not correctly handle string event fields that were no...

CVE-2026-64359

A flaw was found in the Linux kernel's nilfs2 filesystem. This vulnerability occurs because user-supplied segment numbers are not properly validated before processing CLEANSEGMENTS ioctl requests. An attacker, by providing out-of-range segment numbers, can trigger excessive logging. This prolonge...

CVE-2026-64337

A flaw was found in the Linux kernel's USB mtu3 gadget driver. When the mtu3gadgetqueue function encounters a failure during the preparation of a USB transfer, the associated Direct Memory Access DMA mapping is not properly released. This leaves the DMA mapping active, which can lead to a resourc...

CVE-2026-64403

A flaw was found in the Bluetooth L2CAP Logical Link Control and Adaptation Protocol component of the Linux kernel. The l2capgetconfopt function, responsible for processing configuration options, does not properly validate the length of an option before attempting to read its value. This allows a...

CVE-2026-64318

A flaw was found in the Linux kernel's AIX partition handling. A local attacker can provide a specially crafted AIX/IBM partition table on a block device. When the kernel scans this device, the aixpartition function reads an unvalidated ppcount value, causing it to read beyond the allocated buffe...

CVE-2026-64409

A flaw was found in the Linux kernel's Bluetooth MTK SDIO btmtksdio driver. An incorrect timeout check in the btmtksdiotxrxwork function can lead to an infinite loop. This prevents the loop from terminating and releasing the SDIO host, resulting in a denial of service DoS where the system resourc...

CVE-2026-64367

A flaw was found in the Linux kernel's hid-goodix-spi driver. This vulnerability, a stack buffer overflow, allows a local attacker to provide an oversized report to the system. This can lead to a buffer overflow, potentially enabling the attacker to execute arbitrary code with elevated privileges...

CVE-2026-64387

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability, a double-free error, occurs when the client attempts to free the same memory buffer twice during a directory query operation. An attacker could potentially exploit this flaw to cause memory corruption,...

CVE-2026-64352

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. When certain security modules interact with network routing tables, it can trigger diagnostic warnings. This issue primarily affects debug kernels by generating console messages and does not lead to direct security...

CVE-2026-64482

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA Gravis Ultrasound GUS driver. When memory allocation fails, the sndctlnew1 function can return a null value. The sndgf1pcmvolumecontrol function does not properly check for this null return, leading to a null pointer...
