——0Issue summary: A retransmitted QUIC CRYPTO frame can release packet storage
while the TLS record layer retains a direct pointer into that storage causing
use after free.
Impact summary: A malicious QUIC server can cause a heap-use-after-free read
in the OpenSSL QUIC client. The server can also identify one allocator-adjacent
byte through the client's protected Handshake response.
CWE: CWE-416: Use After Free
Description: During CRYPTO stream processing, a pointer into the first frame's
memory on the stream is lent to the TLS handshake processing. The memory
must remain stable until it is processed and released. However the processing
of retransmitted CRYPTO frames could release the memory if the retransmitted
frame fully overlapped the existing frame. This then causes use-after-free read
when the TLS handshake processing continues.
The use-after-free read can lead to a Denial-of-Service of the client
application or a minor leak of information about the heap memory contents
that might be overwritten with other data, subsequently allocated by
the application, to the peer.
FIPS impact: no
The FIPS module is not affected as the QUIC implementation is outside of
the OpenSSL FIPS module boundary.9hCVE-2026-945277.8 HIG—
——0Heap-based buffer overflow in Windows GDI allows an authorized attacker to elevate privileges locally.6hCVE-2026-945257.0 HIG—
——0An elevation of privilege vulnerability exists in Windows Error Reporting (WER) when WER handles and executes files. The vulnerability could allow elevation of privilege if an attacker can successfully exploit it.
An attacker who successfully exploited the vulnerability could gain greater access to sensitive information and system functionality. To exploit the vulnerability, an attacker could run a specially crafted application.
The security update addresses the vulnerability by correcting the way that WER handles and executes files.5hCVE-2026-945227.0 HIG—

——0Heap-based buffer overflow in Windows Advanced Rasterization Platform allows an authorized attacker to elevate privileges locally.6hCVE-2026-124946——
——0Invalid pointer in the JavaScript Engine: JIT component. This vulnerability was fixed in Firefox 160 and Thunderbird 160.12hCVE-2026-945077.8 HIG—
——0Heap-based buffer overflow in Windows DirectX allows an authorized attacker to elevate privileges locally.6hCVE-2026-88822——
——0Issue summary: QUIC, when performing automated peer detection, may allow
uninitialized stack data to leak into the received address which is then used
as the destination for outgoing packets.
Impact summary: Applications using QUIC's automated peer detection mechanism
may receive an invalid address, leading to connection loss and disclosure of
uninitialized stack data to an attacker observing the outgoing network traffic.
CWE: CWE-457 (Use of Uninitialized Variable)
Description: The OpenSSL QUIC stack contains a feature in which, when using an
already connected socket, it will auto-detect the peer address during the SSL
handshake. This feature uses the getpeername() function, passing a buffer of
sufficient length to hold any supported address family, but passes a buffer
length that is only sized such that larger addresses, such as IPv6, cannot be
retrieved. The getpeername() function however, still returns the full address
length, which is accepted as the valid input buffer length, leading to the
address buffer containing uninitialized stack data instead of the actual peer
address. The invalid peer address is then used as destination for the outgoing
packets which leads to a connectivity breakage and a leakage of the
uninitialized stack data to passive network observers.
FIPS impact: no
The FIPS modules in 4.0, 3.6, 3.5, 3.4, and 3.0 are not affected by this CVE as
the affected protocol is not implemented in the FIPS module.9hCVE-2026-882498.8 HIG—
