When curl retrieves an HTTP response, it stores the incoming headers so that they can be accessed later via the libcurl headers API. However, curl did not have a limit in how many or how large headers it would accept in a response, allowing a malicious server to stream an endless series of header...

BIT-RCLONE-2026-71310 rclone: Unbounded HTTP CONNECT Response Headers Can Exhaust rclone Memory

rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.75.0, the shared HTTP CONNECT helper in lib/proxy/http.go parses proxy CONNECT responses with http.ReadResponse over an unrestricted buffered reader, allowing a malicious or...

Unity Linux 20.1070e Security Update: rubygem-excon (UTSA-2026-099493)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-099493 advisory. Excon is usable, fast, simple HTTP 1.1 for Ruby. Prior to 1.5.0, Excon's RedirectFollower middleware failed to strip additional sensitive headers when following...

Unity Linux 20.1070a Security Update: bcc (UTSA-2026-099556)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-099556 advisory. If kernel headers need to be extracted, bcc will attempt to load them from a temporary directory. An unprivileged attacker could use this to force bcc to load...

CVE-2026-72348

In the Linux kernel, the following vulnerability has been resolved: netfilter: ip6tables: mark malformed IPv6 extension headers for hotdrop The ah, hbh and rt matches check that the fixed extension header is present, then use the header length field to derive the advertised extension header lengt...

CVE-2026-72417

In the Linux kernel, the following vulnerability has been resolved: netfilter: flowtable: Validate iph-ihl in nfflowip4tunnelproto Add sanity check for iph-ihl field in nfflowip4tunnelproto before using it to compute the header size, avoiding out-of-bounds access with malformed IP headers. While ...

CVE-2026-72021

In the Linux kernel, the following vulnerability has been resolved: ipvs: use parsed transport offset in SCTP state lookup setsctpstate reads the SCTP chunk header again in order to drive the IPVS SCTP state table. For IPv6 it computes the offset with sizeofstruct ipv6hdr, while the surrounding...

CVE-2026-72348

The CVE-2026-72348 entry concerns the Linux kernel netfilter ip6tables handling of IPv6 extension headers (ah, hbh, rt). The issue stems from checks that derive the advertised extension header length from header length fields; improper advertised-length checks allowed malformed headers to bypass ...

In the Linux kernel, the following vulnerability has been resolved: netfilter: ip6tables: mark malformed IPv6 extension headers for hotdrop The ah, hbh and rt matches check that the fixed extension header is present, then use the header length field to derive the advertised extension header lengt...

CVE-2026-72319

The CVE-2026-72319 entry describes a Linux kernel vulnerability in IPVS where inner IP headers in ICMP errors must be kept within skb headroom after removing outer headers (pskb_pull). The root cause involves ensuring the inner headers remain present for functions such as ipv4_update_pmtu(), icmp...

CVE-2026-72021

Summary: The CVE-2026-72021 issue affects the Linux kernel’s IPVS SCTP state lookup. The kernel incorrectly read the SCTP chunk header using a wrong offset for IPv6 when extension headers were present, causing misclassification of handshake steps (e.g., INIT1 vs ESTABLISHED) and incorrect managem...
