| CVE-2026-90463 | 1 Redhat | 3 Enterprise Linux, Openshift, Rhel Els | 2026-11-06 | 4 Medium |
| A flaw was found in the sssd NSS responder. This input validation vulnerability allows a local attacker, by sending specially crafted service lookup requests to the NSS responder's UNIX socket, to cause an out-of-bounds read. This out-of-bounds read may lead to a denial of service (DoS) by crashing the NSS responder process. While unprivileged local clients can typically reach the socket, there is no evidence of privilege escalation or reliable data disclosure. | ||||
| CVE-2026-85498 | 2 Polkit Project, Redhat | 5 Polkit, Enterprise Linux, Hummingbird and 2 more | 2026-11-06 | 3.5 Low |
| A flaw was found in polkit. When processing input that begins with a null byte, an arithmetic error in the authentication agent helper causes an integer underflow during buffer length calculation, resulting in an out-of-bounds memory read. An attacker capable of supplying crafted input can trigger this flaw, potentially causing an application crash and resulting in a Denial of Service (DoS). | ||||
| CVE-2026-59842 | 2 Libssh, Redhat | 12 Libssh, Enterprise Linux, Enterprise Linux For Els and 9 more | 2026-11-06 | 3.7 Low |
| A flaw was found in libssh. During server-side GSSAPI key exchange, a client-supplied Curve25519 public key shorter than the expected length is copied without proper length validation, leading to an out-of-bounds heap read. This could allow a remote unauthenticated attacker to disclose small amounts of server memory. | ||||
| CVE-2026-93524 | 1 X.org | 3 X Server, Xorg-x11-server, Xwayland | 2026-11-06 | 3.3 Low |
| A buffer overread in CheckKeySyms() in X.Org X Server before 21.1.25 and XWayland before 24.1.14 could be used by authenticated X clients to leak small amounts of information from X server memory or potentially crash the X server. | ||||
| CVE-2026-118237 | 1 Github | 1 Enterprise Server | 2026-11-06 | N/A |
| An out-of-bounds read vulnerability was identified in GitHub Enterprise Server in the Git service (babeld). When proving possession of a host key, babeld's SSH implementation sized the session identifier by the current digest length rather than its own. An attacker with an account and SSH access could re-key to an algorithm with a longer hash, causing adjacent process memory to be signed and returned to the client, where a limited amount of it may be recoverable. This vulnerability affected all releases prior to 3.23 and was fixed in versions 3.22.3, 3.21.8, 3.20.10, and 3.19.14. This vulnerability was reported via the GitHub Bug Bounty program. | ||||
| CVE-2026-113938 | 1 Apple | 1 Macos | 2026-11-06 | 5.5 Medium |
| An out-of-bounds read was addressed with improved bounds checking. This issue is fixed in macOS Golden Gate 27.2. An app may be able to cause unexpected system termination. | ||||
| CVE-2026-55654 | 3 Openbsd, Openssh, Redhat | 9 Openssh, Openssh, Enterprise Linux and 6 more | 2026-11-06 | 3.7 Low |
| A flaw was found in OpenSSH. This vulnerability, a heap out-of-bounds read, occurs during the cleanup of GSSAPI (Generic Security Service Application Programming Interface) indicators when a trailing NULL termination is missing in the auth-indicators array. A remote attacker, under specific configurations involving GSSAPI authentication and a Kerberos environment, could exploit this to cause the SSH authentication path to crash or abort. This leads to a denial of service (DoS), impacting the availability of the SSH service. | ||||
| CVE-2026-112554 | 1 Apple | 4 Ios And Ipados, Ipados, Iphone Os and 1 more | 2026-11-06 | 7.5 High |
| An out-of-bounds read was addressed with improved bounds checking. This issue is fixed in iOS 26.7.2 and iPadOS 26.7.2, iOS 27.2 and iPadOS 27.2, macOS Golden Gate 27.2, macOS Sequoia 15.8.2, macOS Tahoe 26.7.2. An app may be able to cause unexpected system termination or read kernel memory. | ||||
| CVE-2026-92693 | 1 Pavel-odintsov | 1 Fastnetmon | 2026-11-06 | 8.2 High |
| FastNetMon is a high-performance DDoS detector and sensor. In version 1.2.9 and earlier, parse_raw_packet_to_simple_packet_full() in src/simple_packet_parser_ng.cpp dereferences ipv6_extension_header_fragment_t when IpProtocolNumberIPV6_FRAG is present without first verifying that the eight-byte Fragment header remains. A crafted sFlow v5 RAW_PACKET_HEADER record can remotely reach this shared parser with the Fragment bytes omitted, causing an unauthenticated remote out-of-bounds read. The supplied harness detects the read under AddressSanitizer, but the advisory does not establish a production process crash. No fixed release is available as of this review. | ||||
| CVE-2026-123269 | 1 Libyal | 1 Libvmdk | 2026-11-06 | 3.3 Low |
| A vulnerability was detected in libyal libvmdk. Affected by this vulnerability is the function libvmdk_descriptor_file_read_header of the file libvmdk/libvmdk_descriptor_file.c of the component Descriptor File Parser. The manipulation results in out-of-bounds read. The attack must be initiated from a local position. The exploit is now public and may be used. The patch is identified as 175d3fc0a0b961f362f16e7560a6169d7213e16b. It is best practice to apply a patch to resolve this issue. | ||||
| CVE-2026-113935 | 1 Apple | 1 Macos | 2026-11-06 | 5.5 Medium |
| An out-of-bounds read was addressed with improved bounds checking. This issue is fixed in macOS Golden Gate 27.2. An app may be able to cause unexpected system termination. | ||||
| CVE-2026-117635 | 1 Gitea | 1 Gitea | 2026-11-06 | 6.5 Medium |
| The `/api/v1/admin` route group did not enforce the `public-only` restriction of personal access tokens. A public-only token with admin scope issued by a site administrator could therefore list private organizations and the email addresses of all users, create organizations, obtain runner registration tokens and create new site administrator accounts, the last of which persists after the token is revoked. Tokens of users who are not site administrators cannot reach these routes; public-only tokens are now rejected on the admin API. | ||||
| CVE-2026-2443 | 3 Gnome, Red Hat, Redhat | 4 Libsoup, Enterprise Linux, Enterprise Linux and 1 more | 2026-11-06 | 5.3 Medium |
| A flaw was identified in libsoup, a widely used HTTP library in GNOME-based systems. When processing specially crafted HTTP Range headers, the library may improperly validate requested byte ranges. In certain build configurations, this could allow a remote attacker to access portions of server memory beyond the intended response. Exploitation requires a vulnerable configuration and access to a server using the embedded SoupServer component. | ||||
| CVE-2026-17072 | 2 Gstreamer, Redhat | 3 Good Plug-ins, Enterprise Linux, Rhel Els | 2026-11-06 | 3.3 Low |
| A flaw was found in GStreamer's gst-plugins-good. A heap-based out-of-bounds read of 4 bytes can occur when parsing FLAC audio stream headers embedded in a Matroska or WebM container file. The vulnerability is triggered by a boundary check that does not account for the full size of the data being copied, allowing a small read past the end of the allocated buffer. An attacker could exploit this by crafting a malicious Matroska or WebM file and tricking a user into opening it, potentially leaking a small amount of adjacent heap memory. | ||||
| CVE-2026-18747 | 1 Zephyrproject | 1 Zephyr | 2026-11-06 | 6.8 Medium |
| The MCUmgr SMP-over-console transport decodes a base64 frame, reads a 16-bit packet length from it, verifies a CRC and then unconditionally strips the trailing CRC with rx_ctxt->nb->len -= 2U; in mcumgr_serial_process_frag() (subsys/mgmt/mcumgr/transport/src/serial_util.c). mcumgr_serial_extract_len() accepted any declared length, including 0 and 1, and a packet declaring length 0 passes the checksum test for free because crc16_itu_t() over zero bytes returns the zero seed. Since net_buf::len is a uint16_t, the subtraction underflows and the buffer is handed to SMP claiming roughly 65 KB of payload while its data area is only CONFIG_MCUMGR_TRANSPORT_NETBUF_SIZE bytes (default 384). The trigger is a single unauthenticated 7-byte line on the management console — the 0x06 0x09 packet marker followed by the base64 group AAA= and a newline — delivered to any transport built on this helper: CONFIG_MCUMGR_TRANSPORT_UART (smp_uart.c) or CONFIG_MCUMGR_TRANSPORT_SHELL (smp_shell.c), both of which select MCUMGR_TRANSPORT_SERIAL_HAS_SMP_OVER_CONSOLE. No prior session state, fragmentation or credentials are required to trigger the underflow, and the malformed frame is mishandled before any command handler or command-level access control runs. The attacker only needs write access to that console, which on many boards is a USB CDC-ACM port rather than a bare UART header. With the inflated length, smp_process_request_packet() in subsys/mgmt/mcumgr/smp/src/smp.c loses its bound: cbor_nb_reader_init() gives the CBOR decoder a ~65 KB window into a 384-byte buffer, and each request header's nh_len is checked only against the inflated length. On its own the 7-byte frame re-parses whatever stale bytes the reused pool buffer still holds, typically a replay of the previously received request followed by a parse error, without leaving the buffer. Because the transport is unauthenticated, though, the attacker also controls the frames sent before the trigger, and can stage buffer contents so that a request succeeds with an nh_len larger than the buffer; net_buf_pull(), guarded only by __ASSERT_NO_MSG, then moves the parse cursor out of bounds and the loop reads further headers and CBOR from adjacent memory. The consequence is an out-of-bounds read that can fault the MCUmgr thread (denial of service); memory disclosure is also possible, since the default-enabled os echo handler (CONFIG_MCUMGR_GRP_OS_ECHO) decodes its string inside that window and copies it into its response. There is no integrity gain beyond what the unauthenticated transport already permits. The fix rejects any declared packet length of two bytes or fewer in mcumgr_serial_extract_len(), so the CRC-strip subtraction can no longer underflow. The identical pattern remains in the test-only loopback transport subsys/mgmt/mcumgr/transport/src/smp_dummy.c (CONFIG_MCUMGR_TRANSPORT_DUMMY), which has no external input path and therefore carries no practical exposure. | ||||
| CVE-2026-12969 | 3 Dnsmasq, Redhat, Thekelleys | 6 Dnsmasq, Enterprise Linux, Openshift and 3 more | 2026-11-06 | 5.3 Medium |
| An out-of-bounds read vulnerability exists in dnsmasq's find_soa() function in src/rfc1035.c. When parsing NS section records, extract_name() is called with extrabytes=0, failing to validate that 10 additional bytes exist for fixed-length DNS record fields. A remote attacker controlling a DNS zone can exploit this via a crafted NXDOMAIN response to cause a 10-byte heap out-of-bounds read, potentially accessing stale data from prior transactions. | ||||
| CVE-2026-2243 | 2 Red Hat, Redhat | 5 Enterprise Linux, Enterprise Linux, Openshift and 2 more | 2026-11-06 | 5.1 Medium |
| A flaw was found in QEMU. A specially crafted VMDK image could trigger an out-of-bounds read vulnerability, potentially leading to a 12-byte leak of sensitive information or a denial of service condition (DoS). | ||||
| CVE-2026-15712 | 1 Redhat | 1 Enterprise Linux | 2026-11-06 | 5.9 Medium |
| A heap buffer over-read vulnerability was discovered in libsoup's (versions: libsoup 3.0 to 3.7.0) HTTP/2 connection tracking framework. When the library processes an HTTP/2 GOAWAY frame, it improperly handles the "Additional Debug Data" payload by assuming the data stream is a safely NUL-terminated C-string. Because the parser lacks strict length-boundary verification before reading this data, a remote, unauthenticated attacker can intentionally send a malformed GOAWAY frame missing the appropriate null delimiter. This causes the library to read past the end of the allocated buffer, triggering an application crash that results in a denial of service (DoS), or potentially exposing fragments of memory contents. | ||||
| CVE-2026-1485 | 1 Redhat | 3 Enterprise Linux, Openshift Ai, Rhel Els | 2026-11-06 | 2.8 Low |
| A flaw was found in Glib's content type parsing logic. This buffer underflow vulnerability occurs because the length of a header line is stored in a signed integer, which can lead to integer wraparound for very large inputs. This results in pointer underflow and out-of-bounds memory access. Exploitation requires a local user to install or process a specially crafted treemagic file, which can lead to local denial of service or application instability. | ||||
| CVE-2025-60018 | 1 Redhat | 2 Enterprise Linux, Rhel Els | 2026-11-06 | 4.8 Medium |
| glib-networking's OpenSSL backend fails to properly check the return value of a call to BIO_write(), resulting in an out of bounds read. | ||||
