New Interrupt Injection Attack Can Bypass Spectre v2 Defenses on Intel and AMD CPUs

An unprivileged Linux program can time a hardware interrupt to land in the gap between a processor sanitizing its branch predictor and the kernel using it, re-poisoning the predictor after the defense has run. MIT CSAIL researchersDaniël Trujillo and Mengjia Yan named the technique INTERRUPT...

The vulnerabilities in the net/bluetooth/eir.c and net/bluetooth/mgmt.c modules of Linux kernel allow a hacker to cause a service failure.

The vulnerability in the net/bluetooth/eir.c and net/bluetooth/mgmt.c modules of Linux kernel systems relates to the execution of operations beyond the buffer boundaries in memory. Exploiting this vulnerability can allow an attacker to cause a system failure...

CVE-2026-64572

A flaw was found in the Linux kernel's IPv4 forwarding information base FIB component. A local attacker with administrative network capabilities CAPNETADMIN could exploit a timing issue during route insertion and lookup operations. This could lead to a "use-after-free" vulnerability, where the...

CVE-2026-64578

A flaw was found in ksmbd, a Linux kernel module that provides an in-kernel SMB3 server. A remote attacker could exploit this vulnerability by crafting a malicious compound SMB2 request. This improper validation of the request size before reading specific data could lead to an out-of-bounds read,...

CVE-2026-64571

A flaw was found in the Linux kernel's wifi: p54 component. A local attacker with a malicious USB device could exploit this by sending a specially crafted frame during an EEPROM Electrically Erasable Programmable Read-Only Memory readback operation. This vulnerability allows the device to read...

CVE-2026-64566

A flaw was found in the Linux kernel's iptfs module, which handles network packet processing. When copying shared packet fragments, a critical flag indicating shared memory is not correctly propagated. This can lead to memory corruption within the kernel, potentially causing the system to crash a...

CVE-2026-55978

An improper access control vulnerability in CatchPulse could allow a non-administrative local attacker to connect to an unrestricted kernel filter communication port and bypass CatchPulse's security policy enforcement...

CVE-2026-64574

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. When new Wi-Fi links are added, an error in the update process can cause debugfs entries to point to memory that has already been freed. A local attacker can exploit this use-after-free vulnerability by accessing these dangling...

CVE-2026-64569

A flaw was found in the Linux kernel's Multiprotocol Label Switching MPLS subsystem. An unprivileged local user could send a specially crafted network message, leading to a null pointer dereference. This vulnerability could cause a system crash, resulting in a denial of service...

CVE-2026-64579

A flaw was found in the Linux kernel's xfrm policy component. An issue in the xfrmhashrebuild function, specifically with the preallocation of inexact policy bins, can lead to memory allocation failures under memory pressure. This failure can corrupt internal data structures, allowing a local...

CVE-2026-55978

CVE-2026-55978 describes an improper access control vulnerability in CatchPulse that could allow a non-administrative local attacker to connect to an unrestricted kernel filter communication port and bypass CatchPulse’s security policy enforcement. The NVD entry indicates a local attack vector wi...

CVE-2026-55978 Improper access control vulnerability in CatchPulse

An improper access control vulnerability in CatchPulse could allow a non-administrative local attacker to connect to an unrestricted kernel filter communication port and bypass CatchPulse's security policy enforcement...

CVE-2026-64604

CVE-2026-64604 concerns the Linux kernel KVM VMX path, where CR8 intercept updates are performed: the VMCS12 state is grabbed only when the vCPU is in guest mode to avoid a lockdep assertion in get_vmcs12(). The provided description and call trace show that the issue arises during vCPU creation a...

EUVD-2026-53789

In the Linux kernel, the following vulnerability has been resolved: platform/x86: intel-hid: Protect ACPI notify handler against recursion Since commit e2ffcda16290 "ACPI: OSL: Allow Notify handlers to run on all CPUs" ACPI notify handlers like the intel-hid notifyhandler may run on multiple CPU...

EUVD-2026-53790

In the Linux kernel, the following vulnerability has been resolved: KVM: VMX: Grab vmcs12 on CR8 interception update iff vCPU is in guest mode When updating CR8 intercepts, get vmcs12 if and only if the vCPU is in guest mode so that a future change can have update CR8 intercepts during vCPU...

CVE-2026-64603

The CVE-2026-64603 entry describes a race condition in the Linux kernel's intel-hid platform/x86 ACPI notify_handler(). When two ACPI notify events race on different CPUs during lazy registration of the SW_TABLET_MODE input device (triggered from intel_hid_switches_setup()), both can bypass priv-...

CVE-2026-64602

The CVE describes a race condition in spear_adc_probe() for the Linux kernel IIO SPI driver: devm_request_irq() is called before st->completion is initialized, so an IRQ arriving early may call complete() on an uninitialized completion, dereferencing a NULL list entry and causing a kernel pani...
