CVE-2026-43186

A flaw was found in the Linux kernel's IPv6 In-situ Operations, Administration, and Maintenance IOAM functionality. A remote attacker can send a specially crafted packet that manipulates the nodelen field while processing trace data. This manipulation leads to a heap buffer overflow, causing...

CVE-2026-33975

Twenty is an open source CRM built with NestJS Node.js. In versions 1.18.0 and earlier, the SSRF protection in twenty-server's SecureHttpClientService can be bypassed using IPv4-mapped IPv6 addresses in URL IP literals. Node.js's URL parser normalizes IPv4-mapped IPv6 addresses to compressed hex...

Incomplete Filtering of Special Elements

Overview dssrf is a SSRF defense library for Node.js with safe URL validation utilities. Affected versions of this package are vulnerable to Incomplete Filtering of Special Elements via the isurlsafe function. An attacker can access internal network resources by supplying specially crafted IPv6...

CVE-2026-43088

A flaw was found in the Linux kernel's AFKEY networking component. When handling PFKEY export paths, the pfkeysockaddrfill function does not fully initialize sockaddrin6 structures, leaving 4 bytes of memory uninitialized. This can lead to the disclosure of potentially sensitive information from...

CVE-2026-43101

A flaw was found in the Linux kernel's IPv6 In-situ Operations, Administration, and Maintenance IOAM subsystem. The ioam6filltracedata function did not properly check for NULL values, which could lead to NULL dereferences. A local or remote attacker could potentially trigger this flaw, resulting ...

EUVD-2026-27698

In the Linux kernel, the following vulnerability has been resolved: xfrm6: fix uninitialized saddr in xfrm6getsaddr xfrm6getsaddr does not check the return value of ipv6devgetsaddr. When ipv6devgetsaddr fails to find a suitable source address returns -EADDRNOTAVAIL, saddr-in6 is left uninitialize...

EUVD-2026-27608

In the Linux kernel, the following vulnerability has been resolved: ipv4: icmp: fix null-ptr-deref in icmpbuildprobe ipv6stub-ipv6devfind may return ERRPTR-EAFNOSUPPORT when the IPv6 stack is not active CONFIGIPV6=m and not loaded, and passing this error pointer to devhold will cause a kernel cra...

EUVD-2026-27586

In the Linux kernel, the following vulnerability has been resolved: net: afkey: zero aligned sockaddr tail in PFKEY exports PFKEY export paths use pfkeysockaddrsize when reserving sockaddr payload space, so IPv6 addresses occupy 32 bytes on the wire. However, pfkeysockaddrfill initializes only th...

AZL-85803 CVE-2026-43198 affecting package kernel 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: tcp: fix potential race in tcpv6synrecvsock Code in tcpv6synrecvsock after the call to tcpv4synrecvsock is done too late. After tcpv4synrecvsock, the child socket is already visible from TCP ehash table and other cpus might use i...

CVE-2026-43139

In the Linux kernel, the following vulnerability has been resolved: xfrm6: fix uninitialized saddr in xfrm6getsaddr xfrm6getsaddr does not check the return value of ipv6devgetsaddr. When ipv6devgetsaddr fails to find a suitable source address returns -EADDRNOTAVAIL, saddr-in6 is left uninitialize...

CVE-2026-43198 tcp: fix potential race in tcp_v6_syn_recv_sock()

In the Linux kernel, the following vulnerability has been resolved: tcp: fix potential race in tcpv6synrecvsock Code in tcpv6synrecvsock after the call to tcpv4synrecvsock is done too late. After tcpv4synrecvsock, the child socket is already visible from TCP ehash table and other cpus might use i...

CVE-2026-43198

CVE-2026-43198 is a Linux kernel race in IPv6 TCP socket handling. The issue occurs in tcp_v6_syn_recv_sock() where the child socket becomes visible before IPv6 state is initialized, allowing other CPUs to access it and potentially triggering instability. The fix moves the problematic code into t...

CVE-2026-43186 ipv6: ioam: fix heap buffer overflow in __ioam6_fill_trace_data()

In the Linux kernel, the following vulnerability has been resolved: ipv6: ioam: fix heap buffer overflow in ioam6filltracedata On the receive path, ioam6filltracedata uses trace-nodelen to decide how much data to write for each node. It trusts this field as-is from the incoming packet, with no...

CVE-2026-43139

In the Linux kernel, the following vulnerability has been resolved: xfrm6: fix uninitialized saddr in xfrm6getsaddr xfrm6getsaddr does not check the return value of ipv6devgetsaddr. When ipv6devgetsaddr fails to find a suitable source address returns -EADDRNOTAVAIL, saddr-in6 is left uninitialize...

CVE-2026-43139 xfrm6: fix uninitialized saddr in xfrm6_get_saddr()

In the Linux kernel, the following vulnerability has been resolved: xfrm6: fix uninitialized saddr in xfrm6getsaddr xfrm6getsaddr does not check the return value of ipv6devgetsaddr.
