AsyncHttpClient: WebSocket handshake continues after a failed Sec-WebSocket-Accept check

The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. Prior to 3.0.12 and 2.16.1, WebSocketHandler.upgrade aborts a handshake whose Sec-WebSocket-Accept value is missing or invalid but continues into pipeline installation and onOpen delivery. Frames coalesced with the invalid 101 response can be decoded and delivered from a peer that did not prove the handshake, although the request future fails and the channel closes. This issue is fixed in versions 3.0.12 and 2.16.1.

Kiteworks Core Missing Authentication for Critical Function

A Kiteworks appliance setup interface did not enforce authentication once the appliance had completed initial configuration. An unauthenticated attacker with network access to the appliance could read and modify a limited set of setup records, including a contact name and email address captured during initial configuration.

KVM: x86/mmu: Check write tracking in all address spaces

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Check write tracking in all address spaces kvm_gfn_is_write_tracked() checks only the supplied memslot, but page tracking is per-address-space and shadow pages are shared across all address spaces. With SMM, a GFN can therefore be write-tracked in one address space and appear untracked through the other. Check the supplied slot first, then the slot for the other address space. This ensures all callers honor write tracking regardless of the active address space. In particular, it prevents mmu_try_to_unsync_pages() from marking an upper-level shadow page unsync and eventually triggering the BUG in pte_list_remove().

net: bcmasp: fix tx_spb_ring_full() checking same slot cnt times

In the Linux kernel, the following vulnerability has been resolved: net: bcmasp: fix tx_spb_ring_full() checking same slot cnt times The loop initialised next_index from intf->tx_spb_index on every iteration, so incr_ring() always produced the same result and only one slot was ever tested. Move the initialisation before the loop so each iteration advances next_index and the function correctly checks that cnt consecutive descriptor slots are available before allowing a new transmission.

CVE-2026-92932

MISP sachertortephp Xml::build() Operator Precedence Bypass Allows Unintended HTTPS SSRF When readFile Is Disabled

In the MISP sachertortephp library, the Xml::build() static method in lib/Cake/Utility/Xml.php contains a logic error in the conditional that gates network-based XML fetching. The original condition was written as: $options['readFile'] && strpos($input, 'http://') === 0 || strpos($input, 'https://') === 0. Because PHP's && operator has higher precedence than ||, the expression is evaluated as ($options['readFile'] && strpos($input, 'http://') === 0) || strpos($input, 'https://') === 0. As a result, when a caller explicitly sets the readFile option to false to disable file and URL reading, an input string beginning with https:// still satisfies the condition and triggers a network fetch via HttpSocket (configured to follow up to 10 redirects). The http:// branch is correctly gated by the readFile flag, but the https:// branch is not. An attacker who can influence the $input parameter passed to Xml::build() can therefore force the application to issue an outbound HTTPS request to an attacker-controlled or internal URL, even though the caller intended to suppress all remote reads. The fetched response is parsed as XML and may be returned to the caller, enabling information disclosure from internal services or external targets. This constitutes a Server-Side Request Forgery (SSRF) weakness with an information-disclosure impact. The vulnerability requires that the code path in Xml::build() be reachable with attacker-controlled input and that the readFile option be set to false (or the caller expects it to be false).

Multiple Cisco Products Snort Application Detection Engine Policy Bypass Vulnerability

Multiple Cisco products are affected by a vulnerability in the Snort application detection engine that could allow an unauthenticated, remote attacker to bypass the configured policies on an affected system. The vulnerability is due to a flaw in the detection algorithm. An attacker could exploit this vulnerability by sending crafted packets that would flow through an affected system. A successful exploit could allow the attacker to bypass the configured policies and deliver a malicious payload to the protected network.

CVE-2026-7656

Broken IPv6 Neighbor Discovery input validation allows spoofed RA/NS/NA acceptance in Zephyr net stack

The IPv6 Neighbor Discovery handlers in subsys/net/ip/ipv6_nbr.c (handle_ra_input, handle_ns_input, handle_na_input) used an incorrect boolean expression that combined the RFC 4861 validity checks with the ICMPv6 code check using the wrong operator precedence: the form was ((length/hop/source/target checks) && (icmp_hdr->code != 0)). Because every legitimate ND message carries ICMPv6 code 0, an attacker setting code == 0 (the normal value) caused the entire predicate to evaluate false, so the packet was never dropped and all of the other checks were silently skipped. The bypassed checks include the mandatory Hop Limit == 255 verification (which proves an ND packet originated on-link and was not forwarded) and, for Router Advertisements, the requirement that the source be a link-local address, as well as multicast-target sanity checks. As a result, an adjacent on-link attacker — and, because the Hop-Limit-255 guard is bypassed, potentially a remote/off-link attacker whose packets would otherwise be rejected — can have forged Router Advertisement, Neighbor Solicitation, and Neighbor Advertisement messages accepted. A forged RA lets the attacker reconfigure the victim's default router, on-link prefixes (SLAAC), MTU, reachable/retransmit timers, and (with CONFIG_NET_IPV6_RA_RDNSS) DNS servers, while forged NS/NA enable neighbor-cache poisoning, enabling man-in-the-middle, traffic redirection, and denial of service. The flaw is an input-validation/authentication weakness rather than a memory-safety issue: the underlying packet-parsing primitives (net_pkt_get_data, net_pkt_read, net_pkt_skip) are independently bounds-safe and the validated length is the true buffer length, so skipping the length check causes no out-of-bounds access. The defect has existed since the logic was introduced in 2018 and shipped in all releases through v4.4.0; it is fixed by splitting the condition so any failing check drops the packet.

misc: fastrpc: fix list iterator in fastrpc_req_mem_unmap_impl

In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: fix list iterator in fastrpc_req_mem_unmap_impl This is another instance of incorrect use of list iterator and checking it for NULL. The list iterator value 'map' will *always* be set and non-NULL by list_for_each_entry(), so it is incorrect to assume that the iterator value will be NULL if the list is empty (in this case, the check 'if (!map) {' will always be false and never exit as expected). To fix the bug, use a new variable 'iter' as the list iterator, while use the original variable 'map' as a dedicated pointer to point to the found element. Without this patch, Kernel crashes with below trace: Unable to handle kernel access to user memory outside uaccess routines at virtual address 0000ffff7fb03750 ...
