The internet is broken right now.

A security flaw has been discovered in Linksys E5600 1.1.0.26. Affected by this issue is the function init_multipart of the file /cgi-bin/upload_fw.cgi of the component Header Parser. The manipulation results in out-of-bounds write. The attack may be launched remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way. This vulnerability only affects products that are no longer supported by the maintainer.

gopacket provides packet processing capabilities for Go. Prior to 1.7.2, the SCTP chunk chain in layers/sctp.go passes attacker-controlled declared lengths and counts to decodeSCTPInit, decodeSCTPShutdown, decodeSCTPError, decodeSCTPSack, and decodeSCTPParameter without checking that each chunk contains the fixed fields, parameter TLVs, gap acknowledgements, or duplicate TSNs those sub-decoders read. A crafted SCTP segment can therefore cause out-of-bounds or inverted slice panics; the panic can terminate applications that use gopacket.DecodeOptions.SkipDecodeRecovery, direct registered decoders, or DecodingLayerParser with IgnorePanic enabled, while the default recovery-enabled APIs convert it to a per-packet decode error. This is the SCTP sub-decoder residual named but not remediated by CVE-2026-65819, whose version 1.7.1 changes bounded the generic dispatcher but left these per-type reads and loops unchecked. The impact is availability only, with no data disclosure, modification, or allocation amplification. This issue is fixed in version 1.7.2.

Cpanel::JSON::XS versions from 4.20 before 4.80 for Perl write out of bounds when a tied or shared hash grows during canonical encoding in encode_hv. With canonical, the keys of a tied or threads::shared hash are counted before a second pass collects them for sorting. The encoder uses a fixed 64-entry stack array or, for larger counts, a heap array sized from the first pass. If the second pass exceeds that capacity, entries are written out of bounds before the counts are compared. This corrupts stack or heap memory and can crash the process.

odhcpd is the DHCPv6, DHCPv4, and router-advertisement server used by OpenWrt. In versions 25.12 and prior, odhcpd's DHCPv6 self-loop detection at dhcpv6.c:720 uses a network-byte-order DUID length value directly as the memcmp() size parameter. On little-endian hosts, this causes memcmp() to read far beyond the stack buffer — a single unauthenticated DHCPv6 packet triggers a 2560-byte overread from a 128-byte buffer. At time of publication, there are no publicly available patches.

FreeSWITCH is an open-source software telecommunications platform. From 1.10.0 to 1.11.1, there is a stack-based buffer overflow in  mod_sofia  when processing SIP Contact display names for dialog-event notifications. A peer can establish a dialog containing an excessively long display name and subsequently subscribe to that entity’s dialog events, causing the stored value to overflow a fixed 512-byte stack buffer. Exploitation requires presence management to be enabled, directly or through shared appearance, and normally requires valid profile credentials unless subscription authentication is disabled. The overflow can terminate the FreeSWITCH process and all active calls. This vulnerability is fixed in version 1.11.2.
