An attacker with local access could exploit this flaw b...

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...

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: RDMA/vmw_pvrdma: Fix double free on pvrdma_alloc_ucontext() error path

A flaw was found in the Linux kernel, specifically within the RDMA Remote Direct Memory Access vmwpvrdma module. This vulnerability is a double free, which means the system attempts to release the same memory resource twice. This can occur in an error handling path within the pvrdmaallocucontext...

Important: Red Hat Security Advisory: kernel security, bug fix, and enhancement update

An update for kernel is now available for Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support and Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerabilit...

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: smb: client: fix OOB reads parsing symlink error response

A flaw was found in the Linux kernel's Server Message Block SMB client. A remote, untrusted server could send a specially crafted symlink error response, leading to an out-of-bounds read vulnerability. This could result in the disclosure of sensitive information from the kernel's memory to a loca...

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...

CVE-2026-64389

A flaw was found in the Linux kernel's ksmbd component. A remote attacker could exploit a vulnerability in the NTLMv2 authentication process to modify a session key even when authentication fails. This bypasses security checks and could potentially lead to unauthorized access or session hijacking...

CVE-2026-64347

A flaw was found in the USB gadget composite driver in the Linux kernel. An issue with an empty check in the USBDTOTG handler can lead to reading from an invalid memory location. This can result in a kernel AddressSanitizer KASAN fault, potentially causing information disclosure or a denial of...

CVE-2026-64267

A flaw was found in the Linux kernel's Filesystem in Userspace FUSE component. On 32-bit systems, an integer overflow vulnerability exists in the handling of FUSENOTIFYPRUNE messages. A malicious FUSE daemon or a local user could craft a prune notification with a specific count, causing an intege...

CVE-2026-64528

A flaw was found in the Linux kernel's Samsung serial driver. When console flow control is enabled, a redundant attempt to acquire a port lock occurs within the receive helper functions. This can lead to a deadlock on the same CPU, causing the system to become unresponsive...

CVE-2026-64470

A flaw was found in the Linux kernel's Bluetooth USB btusb driver. This vulnerability occurs during the Marvell Out-Of-Band OOB wakeup configuration when a probe failure happens.
