CVE-2026-98239

A flaw was found in the Linux kernel's LAN743x network device driver. This vulnerability allows an attacker capable of transmitting network traffic to an affected system to cause a Denial of Service DoS or memory corruption. The issue occurs because the driver attempts to update checksum...

CVE-2026-19569 Integer overflow in dynamic kernel object allocation allows user-mode threads to corrupt the kernel heap

dynamicobjectcreate in kernel/userspace/userspace.c computed the backing allocation for a dynamically allocated kernel object as objsizegetotype + size, and for thread stack elements as STACKELEMENTDATASIZEsize a round-up plus fixed overhead, without checking either expression for unsigned...

CVE-2026-19574

The ARM64 MMU back-end in Zephyr (specifically in arch_mem_domain_init()) contains a vulnerability where it assigns Address Space Identifiers (ASIDs) using a round-robin counter. Because only 255 ASIDs exist, wrapping the counter allows a new memory domain to share an ASID with a still-live domai...

CVE-2026-19574 ARM64 MMU can assign an in-use ASID to a new memory domain, breaking user-mode memory isolation

The ARM64 MMU back-end allocated address space identifiers ASIDs for memory domains with a bare round-robin counter in archmemdomaininit arch/arm64/core/mmu.c. VMASIDBITS is 8, so only 255 ASIDs exist; once the counter wrapped, archmemdomaininit could hand an ASID to a new domain while a still-li...

EUVD-2026-95527

The ITE IT8xxx2 SHI host-command backend subsys/mgmt/echostcmd/backends/echostcmdbackendshiite.c copied the 8-byte host-command request header from the SPI Rx FIFO directly into the shared receive buffer data-inmsg and only afterwards checked the protocol version and the derived packet length. Th...

The LE Audio Broadcast Sink in subsys/bluetooth/audio/bapbroadcastsink.c copies subgroup metadata from a received Basic Audio Announcement BASE into the static Broadcast Audio Scan Service parameter structure modsrcparam without any bounds check. In basesubgroupmetacb the destination element was...

Vulnerability handling in Citrix NetScaler ADC and Gateway

Citrix has identified a vulnerability in NetScaler ADC and Gateway products when these are configured as SAML Service Providers SPs or Identity Providers IdPs. The vulnerability involves a memory overflow that occurs during the processing of SAML messages. This vulnerability can be activated...

Improper Input Validation

Hazelcast is vulnerable to Improper Input Validation. The vulnerability is due to improper validation of data supplied by a malicious client connected to the cluster, which allows an attacker to read arbitrary memory from a cluster member, crash the member, or potentially corrupt memory and execu...

CVE-2026-98234

A flaw was found in the Linux kernel's Heavy-Hitter Filter HHF network packet scheduler. A local user with network administration privileges, such as within a container or user namespace, can set an excessively large flow limit due to missing upper-bound validation. When the system subsequently...
