| CVE-2026-50258 | 2 Redhat, X.org | 10 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 7 more | 2026-11-04 | 7.8 High |
| A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. The X server has multiple stack buffers sized XkbMaxShiftLevel * XkbNumKbdGroups but CheckKeyTypes() does not verify or clamp non-canonical key types to XkbMaxShiftLevel. A client can change key types to excessive shift levels and trigger stack overflows. This is caused by an incomplete fix of CVE-2025-26597. This may be used to crash the server, or for privilege escalation if the X server runs as root. | ||||
| CVE-2026-50259 | 3 Redhat, X.org, Xorg | 12 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 9 more | 2026-11-04 | 7.8 High |
| A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. _XkbSetMapChecks() declares a fixed-size stack buffer mapWidths[256] indexed by key type index. The helper function CheckKeyTypes() writes to this buffer at a client-controlled offset, allowing a stack buffer overflow. This may be used to crash the server, or for privilege escalation if the X server runs as root. | ||||
| CVE-2026-50256 | 2 Redhat, X.org | 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more | 2026-11-04 | 7.8 High |
| A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. A mismatch between the X server and the libXfont2 library's maximum font name length can cause a stack buffer overflow during font alias resolution. The server allocates a 256 byte stack buffer but libXfont2's alias target name length is 1024 bytes. A font alias name between 257 and 1023 bytes causes the X server to copy that name into the undersized stack buffer without further checks. This may be used to crash the server, or for privilege escalation if the X server runs as root. | ||||
| CVE-2026-48863 | 2 Libsolv, Redhat | 7 Libsolv, Enterprise Linux, Hummingbird and 4 more | 2026-11-04 | 7.5 High |

| CVE-2026-120830 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-11-04 | 7.4 High |
| A flaw was found in libslirp in icmp_forward_error(). When building an ICMP error response, the length of the quoted original IPv4 packet was taken from the IP header without clamping it to the actual buffer length. A truncated or malformed packet could cause an out-of-bounds heap read, leaking host memory into the ICMP error packet returned to a guest or container. | ||||
| CVE-2026-119528 | 2 Red Hat, Redhat | 3 Enterprise Linux, Enterprise Linux, Rhel Els | 2026-11-04 | 7.8 High |
| A flaw was found in GIMP. The PSD plug-in’s image resource header loader uses an incorrect destination size when copying a converted resource name into a fixed stack buffer. Opening a crafted PSD file can cause a stack-based buffer overflow, leading to a crash and potentially arbitrary code execution. | ||||
| CVE-2026-12912 | 2 Libtiff, Redhat | 12 Libtiff, Enterprise Linux, Enterprise Linux Eus and 9 more | 2026-11-04 | 7.3 High |
| A flaw was found in libtiff. A remote attacker could exploit this vulnerability by providing a specially crafted PixarLog-compressed TIFF image. This issue occurs when decoding Pixarlog codec images with the PIXARLOGDATAFMT_8BITABGR output format and a specific stride value, leading to a heap-based buffer overflow. This could potentially result in arbitrary code execution or a denial of service (DoS). | ||||
| CVE-2026-15722 | 1 Redhat | 12 389 Directory Server, Directory Server, Directory Server E4s and 9 more | 2026-11-04 | 7.5 High |
| A stack buffer overflow flaw was found in 389 Directory Server (389-ds-base). The get_ruvelement_from_berval() function in repl5_ruv.c copies digit characters from a network-supplied RUV berval into a fixed 16-byte stack buffer without bounds checking. A remote unauthenticated attacker can crash the LDAP server by sending a crafted StartNSDS50ReplicationRequest extended operation containing a replica ID field with more than 16 digit characters. The overflow occurs during payload decoding, before any authorization check. Stack protectors limit impact to denial of service. | ||||
| CVE-2025-66287 | 1 Redhat | 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more | 2026-11-04 | 8.8 High |
| A flaw was found in WebKitGTK. Processing malicious web content can cause an unexpected process crash due to improper memory handling. | ||||
| CVE-2026-112260 | 2 Gimp, Redhat | 3 Gimp, Enterprise Linux, Rhel Els | 2026-11-04 | 7.1 High |
| A flaw was found in GIMP. Opening a crafted XCF with a malformed text-layer parasite can cause a heap out-of-bounds read, disclosing adjacent heap data into layer text and causing denial of service. | ||||
| CVE-2026-11610 | 1 Redhat | 10 Directory Server, Directory Server E4s, Enterprise Linux and 7 more | 2026-11-04 | 8.8 High |
| A heap buffer overflow flaw was found in the SASL I/O layer of 389 Directory Server (389-ds-base). After a successful SASL bind with integrity protection (SSF > 0), an authenticated attacker can send a specially crafted oversized LDAP UNBIND packet that is copied into a 512-byte heap receive buffer without a bounds check in sasl_io_recv() in sasl_io.c. This allows up to approximately 2 megabytes of attacker-controlled data to overflow the buffer, causing a denial of service (server crash). In FreeIPA and Red Hat Identity Management deployments, any domain user with a valid Kerberos ticket, any enrolled host, or any service account can trigger this vulnerability over the network after authenticating via GSSAPI. The vulnerable code path has existed since approximately 2013 (389-ds-base 1.3.2) and was not addressed by the CVE-2025-14905 fix, which patched a separate heap overflow in schema.c only. | ||||
| CVE-2026-0719 | 1 Redhat | 9 Enterprise Linux, Enterprise Linux Eus, Openshift Devspaces and 6 more | 2026-11-04 | 8.6 High |
| A flaw was identified in the NTLM authentication handling of the libsoup HTTP library, used by GNOME and other applications for network communication. When processing extremely long passwords, an internal size calculation can overflow due to improper use of signed integers. This results in incorrect memory allocation on the stack, followed by unsafe memory copying. As a result, applications using libsoup may crash unexpectedly, creating a denial-of-service risk. | ||||
| CVE-2025-9900 | 1 Redhat | 10 Ai Inference Server, Discovery, Enterprise Linux and 7 more | 2026-11-04 | 8.8 High |
| A flaw was found in Libtiff. This vulnerability is a "write-what-where" condition, triggered when the library processes a specially crafted TIFF image file. By providing an abnormally large image height value in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user. | ||||
| CVE-2025-8067 | 1 Redhat | 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more | 2026-11-04 | 8.5 High |
| A flaw was found in the Udisks daemon, where it allows unprivileged users to create loop devices using the D-BUS system. This is achieved via the loop device handler, which handles requests sent through the D-BUS interface. As two of the parameters of this handle, it receives the file descriptor list and index specifying the file where the loop device should be backed. The function itself validates the index value to ensure it isn't bigger than the maximum value allowed. However, it fails to validate the lower bound, allowing the index parameter to be a negative value. Under these circumstances, an attacker can cause the UDisks daemon to crash or perform a local privilege escalation by gaining access to files owned by privileged users. | ||||
| CVE-2026-102560 | 3 Gnome, Libsoup, Redhat | 7 Libsoup, Libsoup, Enterprise Linux and 4 more | 2026-11-04 | 8.6 High |
| A flaw was found in libsoup. When the permessage-deflate WebSocket extension compresses a very large outgoing message, truncated size calculations used for GByteArray growth could wrap, causing zlib to write past the allocated buffer and resulting in a heap buffer overflow. | ||||
| CVE-2026-102559 | 3 Gnome, Libsoup, Redhat | 10 Libsoup, Libsoup, Enterprise Linux and 7 more | 2026-11-04 | 8.6 High |
| A flaw was found in libsoup. When constructing a masked WebSocket client frame for a very large outgoing payload, size values passed to GByteArray allocation APIs could be truncated while the masking routine still used the full length, causing a heap buffer overflow. | ||||
