SUSE CVE-2026-63920
In the Linux kernel, the following vulnerability has been resolved: ipv6: validate extension header length before copying to cmsg ip6datagramrecvspecificctl builds IPV6HOPOPTS,DSTOPTS,RTHDR cmsgs and their IPV62292 legacy counterparts by trusting the on-wire hdrlen byte ptr1 when computing the...
CVE-2026-63920
The CVE-2026-63920 entry describes a Linux kernel vulnerability in IPv6 extension header handling. The issue arises when ip6_datagram_recv_specific_ctl() builds IPV6_…cmsgs by trusting on-wire hdrlen (ptr[1]) during put_cmsg() length calculation. Although the write to hdrlen is in-bounds, reading...

SUSE CVE-2026-58058
Nmap through 7.99 does not keep the IPv6 extension-header walk within the captured packet in ipv6getdataprimitive libnetutil/netutil.cc, so the pointer advances past the buffer and the remaining-length computation underflows to a large value. A scanned target or on-path attacker returning a craft...
CVE-2026-58058
A flaw was found in Nmap. A remote attacker or a scanned target can send a specially crafted IPv6 response with a truncated extension header. This can lead to an integer underflow, causing out-of-bounds reads and a denial of service DoS due to a crash during raw IPv6 scans. Mitigation Mitigation...
