CVE-2026-64291

A flaw was found in the Linux kernel's iommufd subsystem. A local user could exploit this vulnerability by allocating excessively large event queues, leading to the exhaustion of kernel memory. This can result in a Denial of Service DoS for the system...

CVE-2026-64503

A flaw was found in the Linux kernel's iio subsystem, specifically in the kxsd9 accelerometer driver. A local user could exploit this by requesting a scale with a non-zero integer part through the kxsd9writeraw function. This action causes a runtime Power Management PM usage-counter reference to...

CVE-2026-64383

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability, a double-free error within the SMB2flush replay mechanism, occurs when the system attempts to free a memory buffer twice. A malicious SMB server could exploit this by sending a specially crafted flush...

CVE-2026-64379

A flaw was found in the Linux kernel's Server Message Block SMB client. When processing server-provided file mode information, the system incorrectly applies these modes without proper security masking. This can result in unintended file permissions, potentially allowing unauthorized access to...

CVE-2026-64301

A flaw was found in the Linux kernel's regulator subsystem. An issue in the scmiregulatorprobe function can lead to a reference count leak. This occurs when an error path is triggered during device node processing, causing a resource to not be properly released. Over time, this unreleased resourc...

CVE-2026-64508

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF Just-In-Time JIT compiler. The BPF JIT allocator reuses memory space, and when new code is written, an indirect jump into the new program can reuse a branch prediction left behind by an old program. This could allow an attacker to...

CVE-2026-64525

A flaw was found in the Linux kernel's xfrm IPSec framework component. An issue with improper RCU Read-Copy-Update synchronization in the xfrmpolicyfini function, specifically the serial execution of synchronizercu for each network namespace during cleanup, can lead to a Denial of Service DoS...

CVE-2026-64405

A flaw was found in the Linux kernel's Bluetooth subsystem, specifically within the hciconn module. This vulnerability occurs when the hciabortconn function attempts to process a pending connection while a critical pointer is unexpectedly null. This can lead to a null pointer dereference, causing...

CVE-2026-64419

A flaw was found in the Linux kernel. A local user could trigger a system crash by reading a specific debugfs "count" file related to memory management. This issue arises because a function attempts to perform an operation that can cause it to pause sleep while holding a critical system lock, whi...

CVE-2026-64486

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA cmipci component. This vulnerability occurs because the sndcmipcispdifcontrols function fails to check the return value of sndctlnew1, which can return a null pointer if memory allocation fails. A local attacker could...

CVE-2026-64279

A flaw was found in the Linux kernel, specifically within its I2C Inter-Integrated Circuit core component. This vulnerability involves a race condition that occurs when an I2C adapter is being removed from the system. During this process, it is possible for the system to attempt to access the...

CVE-2026-64305

A flaw was found in the Linux kernel's cryptographic acceleration qat component. This vulnerability occurs because certain functions iterate over a critical data structure without proper synchronization. If another operation modifies this structure concurrently, it can lead to data corruption or ...

CVE-2026-64330

A flaw was found in the Linux kernel's USB Type-C subsystem tcpm. A malicious USB-C partner device could exploit an out-of-bounds read vulnerability in the svdmconsumemodes function. By manipulating the SVID Standard or Vendor ID index, the partner device can force the system to register an...

CVE-2026-64422

A flaw was found in the Linux kernel's IPv4 networking stack. Invalid values for net.ipv4.tcpreordering, particularly negative inputs, can lead to an integer overflow when processed. When tcpmtuprobing is enabled, this overflow can cause an out-of-bounds read within the tcpmtuprobe function. This...

CVE-2026-64343

A flaw was found in the Linux kernel. A race condition exists in the ldusb USB driver where a mutexunlock operation can attempt to access a mutex structure after it has been freed. This occurs when the release and disconnect functions race, leading to a use-after-free vulnerability. A local...

USN-8623-1: Linux kernel (NVIDIA) 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: - ARM64 architecture; - Arm Firmware Framework for ARMv8-AFFA; CVE-2026-53354, CVE-2026-64520...

USN-8623-1 linux-nvidia-6.17 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: - ARM64 architecture; - Arm Firmware Framework for ARMv8-AFFA; CVE-2026-53354, CVE-2026-64520...

CVE-2026-64374

A flaw was found in the Linux kernel's real-time RT scheduler. In non-real-time configurations, the RTPUSHIPI mechanism, designed to improve task migration, can lead to a live lock. This occurs when a CPU handling heavy network traffic is repeatedly interrupted by other CPUs attempting to schedul...

CVE-2026-64529

A flaw was found in the Linux kernel's QAT QuickAssist Technology driver. Unused character devices and IOCTLs Input/Output Control were exposed, which increased the potential attack surface. Removing these interfaces reduces the risk of future vulnerabilities and improves the overall security...
