CVE-2026-98570 net: ipv6: keep room for the mac header in dst_dev_overhead()

In the Linux kernel, the following vulnerability has been resolved: net: ipv6: keep room for the mac header in dstdevoverhead The seg6, ioam6 and rpl lwtunnels size their skbcowhead request as the length they are about to push plus dstdevoverhead, then push the new headers and rebuild the mac...

CVE-2026-98570

The Linux kernel contains a vulnerability in the ipv6 networking stack related to how dst_dev_overhead() handles headroom. When seg6 , ioam6 , and rpl lwtunnels request skb_cow_head() space, they may not account for sufficient headroom required by skb_mac_header_rebuild(). Specifically, when proc...

CVE-2026-98532

In the Linux kernel, the following vulnerability has been resolved: ipv6: do not let ipv6findhdr return an offset past the packet end ipv6findhdr walks the extension header chain, skipping each header by the length that header itself declares. ipv6optlen returns up to 2048, and the skip is never...

CVE-2026-98532 ipv6: do not let ipv6_find_hdr() return an offset past the packet end

In the Linux kernel, the following vulnerability has been resolved: ipv6: do not let ipv6findhdr return an offset past the packet end ipv6findhdr walks the extension header chain, skipping each header by the length that header itself declares. ipv6optlen returns up to 2048, and the skip is never...

CVE-2026-98532

A flaw in the Linux kernel IPv6 extension header parsing mechanism allows a remote attacker to cause a Denial of Service (DoS) or memory corruption by sending specially crafted IPv6 network packets. The ipv6_find_hdr() function fails to verify that a header's declared length fits within the actua...

CVE-2026-98531

In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: enforce exact attribute length for SEG6ATTRDST In seg6genlpolicy, SEG6ATTRDST is defined with .type = NLABINARY and .len = sizeofstruct in6addr. For NLABINARY, .len only enforces the maximum payload length and permits...

CVE-2026-98531

A vulnerability exists in the Linux kernel where the seg6_genl_policy allows a short SEG6_ATTR_DST attribute because it uses NLA_BINARY with a maximum length check. This allows a 16-byte out-of-bounds read past skb->tail into uninitialized memory during a SEG6_CMD_SET_TUNSRC operation. The lea...

Regular Expression Denial of Service (ReDoS)

Overview ip-address is an A library for parsing IPv4 and IPv6 IP addresses in node and the browser. Affected versions of this package are vulnerable to Regular Expression Denial of Service ReDoS via the Address6 constructor in src/ipv6.ts, where the REZONESTRING regular expression /%.$/ is applie...

CVE-2026-111997

A flaw was found in ip-address. A remote attacker can cause a Denial of Service DoS by providing specially crafted input containing excessive percent characters to an application parsing IPv6 addresses. When processed by the Address6 constructor, inefficient parsing logic leads to high CPU...
