CVE-2026-105483

A flaw in Node.js TLS hostname verification allows an attacker to bypass certificate validation by using non-ASCII fullwidth digits (e.g., １２７.０.０.１) to represent an IP address. The tls.checkServerIdentity() function fails to recognize these as IP addresses, instead matching them against DNS name...

CVE-2026-106069

A flaw in Node.js TLS hostname verification can cause a server certificate to be validated against a different IP address than the one the client connected to, when the host is a non-canonical IPv4 literal with a leading zero, such as 0127.0.0.1. tls.checkServerIdentity normalizes the host...

CVE-2026-105483

A flaw in Node.js TLS hostname verification allows a certificate without a matching IP address SAN to authenticate a connection to an IPv4 address when the host is written with non-ASCII characters, such as fullwidth digits １２７.0.0.1. tls.checkServerIdentity did not recognize such hosts as IP...

CVE-2026-106072

A flaw in Node.js TLS hostname verification allows a certificate with only a DNS SAN to authenticate an IP endpoint when the client connects using a non-canonical IPv4 spelling, such as 0177.0.0.1, 0x7f.0.0.1, 2130706433 or 127.1. tls.checkServerIdentity did not classify these hosts as IP...

CVE-2026-99077

In the Linux kernel, the following vulnerability has been resolved: ipv4: udp: Create exceptions before socket matching Currently, when ICMP Fragmentation Needed and Redirect Message packets are locally delivered and quote a UDP packet, a FIB nexthop exception FNHE is only created if the kernel c...

CVE-2026-99074

The Linux kernel contains a vulnerability where a null-pointer dereference can occur during the PMTU (Path MTU) walk process. The root cause is a race condition: while RCU protects the lifetime of nexthop groups, it does not ensure that fib_info_num_path() and fib_info_nhc() observe the same grou...

CVE-2026-99074

In the Linux kernel, the following vulnerability has been resolved: ipv4: stop PMTU walk when nexthop group shrinks Commit 7d3f3b4367f3 "net: ipv4: Cache pmtu for all packet paths if multipath enabled" made iprtupdatepmtu update every path. For nexthop objects, fibinfonumpath and fibinfonhc...

EUVD-2026-108739

In the Linux kernel, the following vulnerability has been resolved: ipv4: stop exception dump when nexthop group shrinks Commit 4ce5dc9316de "inet: switch inetdumpfib to RCU protection" allowed IPv4 FIB dumps to run concurrently with nexthop replacement. fibdumpinfofnhe uses fibinfonumpath as the...

CVE-2026-99073

The Linux kernel contains a vulnerability where an IPv4 Forwarding Information Base (FIB) dump could lead to a null pointer dereference. The issue occurs because fib_dump_info_fnhe() uses a loop bound that may become invalid if an RTM_NEWNEXTHOP operation replaces a nexthop group with fewer paths...

In the Linux kernel, the following vulnerability has been resolved: ipv4: stop exception dump when nexthop group shrinks Commit 4ce5dc9316de "inet: switch inetdumpfib to RCU protection" allowed IPv4 FIB dumps to run concurrently with nexthop replacement. fibdumpinfofnhe uses fibinfonumpath as the...

EUVD-2026-108738

In the Linux kernel, the following vulnerability has been resolved: ipv4: stop route notification sizing when nexthop group shrinks Commit 680aea08e78c "net: ipv4: Emit notification when fib hardware flags are changed" added an RCU-only fibnlmsgsize call for asynchronous hardware flag...

CVE-2026-99072

A vulnerability exists in the Linux kernel networking stack related to ipv4 route notifications. The issue occurs because fib_nlmsg_size() performs an RCU-only call where fib_info_nhc() independently reloads nh->nh_grp. If RTM_NEWNEXTHOP replaces a group with fewer paths between these two oper...

CVE-2026-99072

In the Linux kernel, the following vulnerability has been resolved: ipv4: stop route notification sizing when nexthop group shrinks Commit 680aea08e78c "net: ipv4: Emit notification when fib hardware flags are changed" added an RCU-only fibnlmsgsize call for asynchronous hardware flag...

EUVD-2026-108737

In the Linux kernel, the following vulnerability has been resolved: ipv4: do not warn on route notification size race Commit 680aea08e78c "net: ipv4: Emit notification when fib hardware flags are changed" added asynchronous route notifications for hardware flag changes. fibaliashwflagsset sizes t...

CVE-2026-99071

The Linux kernel contains a vulnerability related to asynchronous route notifications for hardware flag changes. Specifically, the fib_alias_hw_flags_set() function sizes the socket buffer (skb) using fib_nlmsg_size() and subsequently fills it with fib_dump_info() while only holding RCU. When nex...
