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...

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...
