| CVE-2026-90462 | 3 Fedoraproject, Redhat, Sssd | 6 Sssd, Enterprise Linux, Openshift and 3 more | 2026-11-06 | 5.4 Medium |
| A flaw was found in SSSD. When configured with the LDAP access provider and `ldap_access_order` including `ppolicy` or `lockout`, a fail-open condition in the LDAP ppolicy access check can occur if a user lookup returns zero results. This can incorrectly return success and cache an allow decision, permitting continued authorization for a deleted or deprovisioned user. A remote attacker with prior valid account context could exploit this to maintain access to information and potentially make limited modifications to resources that should no longer be available. | ||||
| CVE-2026-89329 | 1 Redhat | 4 Enterprise Linux, Openshift, Openshift Container Platform and 1 more | 2026-11-06 | 6.2 Medium |
| A flaw was found in `multipathd`. A local attacker with access to the `multipathd` UNIX control socket can exploit this vulnerability by sending valid commands and then ceasing to read replies. This action can cause the `multipathd` listener thread to block, leading to a Denial of Service (DoS) where legitimate Inter-Process Communication (IPC) operations may hang or time out. This issue does not result in privilege escalation, arbitrary code execution, or impact data confidentiality or integrity. | ||||
| CVE-2026-89098 | 2 Nfs, Redhat | 5 Nfs-utils, Enterprise Linux, Openshift and 2 more | 2026-11-06 | 5.5 Medium |
| A flaw was found in nfs-utils. The fsidd daemon improperly handles input received over its local domain socket by relying on program assertions to verify command arguments. A local user can exploit this vulnerability by sending a malformed request lacking the required arguments to trigger an assertion failure. This causes the daemon to crash, resulting in a Denial of Service (DoS) for filesystem identifier lookup services until restarted. | ||||
| CVE-2026-89096 | 2 Nfs, Redhat | 5 Nfs-utils, Enterprise Linux, Openshift and 2 more | 2026-11-06 | 5.9 Medium |
| A flaw was found in nfs-utils. An unauthenticated remote attacker can trigger a Denial of Service (DoS) by sending repeated state notification requests to an exposed rpc.statd service. The service fails to properly release memory allocated during callback processing, leading to continuous memory growth. Sustained requests can exhaust system resources, eventually causing the service to degrade or crash. | ||||
| CVE-2026-89088 | 2 Gparted, Redhat | 3 Gparted, Enterprise Linux, Rhel Els | 2026-11-06 | 5.5 Medium |
| A flaw was found in parted. A heap-based buffer overflow exists in libparted's file system resizing logic when handling FAT16 volumes. By convincing a user or administrator to resize a specially crafted FAT16 file system image with malformed directory metadata, an attacker can trigger an oversized read into a fixed-size memory buffer. This issue causes memory corruption, resulting in an application crash and a denial of service (DoS). | ||||
| CVE-2026-89085 | 2 Gparted, Redhat | 3 Gparted, Enterprise Linux, Rhel Els | 2026-11-06 | 6.6 Medium |
| A flaw was found in parted. A heap-based buffer overflow can occur when processing a specially crafted FAT32 filesystem due to an integer calculation error during buffer allocation. A local attacker could exploit this by enticing a user or automated service to open a malicious filesystem image, resulting in an application crash leading to a Denial of Service (DoS) or potential memory corruption. | ||||
| CVE-2026-88914 | 1 Redhat | 2 Enterprise Linux, Rhel Els | 2026-11-06 | 4.4 Medium |
| A flaw was found in GStreamer's gst-plugins-good isomp4 plugin. When processing a specially crafted MP4 or MOV file containing CEA-608 closed-caption data, an integer overflow in 32-bit unsigned arithmetic can bypass a bounds check in the caption parser. This leads to an out-of-bounds heap read of up to 244 bytes, which is then included in the downstream caption output. An attacker could exploit this by tricking a user into opening a malicious media file, potentially resulting in disclosure of adjacent heap memory or application crash. | ||||
| CVE-2026-88859 | 1 Redhat | 2 Enterprise Linux, Rhel Els | 2026-11-06 | 6.3 Medium |
| A flaw was found in Evolution. A remote attacker can exploit this vulnerability by sending a specially crafted HTML email containing a spoofed vCard control. When a victim clicks on this control, Evolution's trusted JavaScript handler incorrectly assigns an attacker-controlled JavaScript URL to an iframe's source. This action leads to arbitrary JavaScript execution within the mail-viewing context, effectively bypassing the security measures designed to prevent script execution in email content. | ||||
| CVE-2026-88252 | 3 Fedoraproject, Redhat, Sssd | 6 Sssd, Enterprise Linux, Openshift and 3 more | 2026-11-06 | 4.7 Medium |
| A flaw was found in sssd. A local user can cause a Denial of Service (DoS) by exhausting the responder service's available file descriptors (system handles used for open connections). By opening and maintaining many concurrent connections to a responder socket while continuing to queue new connection attempts, an attacker can trigger an unthrottled retry loop. This condition leads to high CPU utilization and stalls the service, preventing legitimate identity and authentication requests from being processed. | ||||
| CVE-2026-87875 | 2 Openprinting, Redhat | 7 Cups, Enterprise Linux, Hardened Images and 4 more | 2026-11-06 | 4.3 Medium |
| The cupsUTF32ToUTF8() function in CUPS's cups/transcode.c lacks a source-length bound and can read past the end of the source buffer, resulting in a heap out-of-bounds read. This is reachable via SNMP supply-description parsing in backend/snmp-supplies.c with attacker-controlled content. | ||||
| CVE-2026-87853 | 2 Redhat, Sssd | 5 Enterprise Linux, Openshift, Openshift Container Platform and 2 more | 2026-11-06 | 7.5 High |
| A flaw was found in SSSD's IdP authentication provider. The eval_access_token_buf() function compares the OIDC subject identifier using strncmp() with the authenticated user's identifier length, performing a prefix comparison instead of an exact match. An attacker whose IdP identifier is a strict prefix of a target user's identifier can authenticate as the target user. | ||||
| CVE-2026-86345 | 1 Redhat | 4 Directory Server, Enterprise Linux, Redhat Directory Server and 1 more | 2026-11-06 | 9 Critical |
| A flaw was found in 389-ds-base. The server does not discard plaintext bytes already buffered from a client connection when negotiating StartTLS, allowing an on-path attacker to inject a crafted LDAP message that is processed after the TLS upgrade and whose response is delivered to the client in place of the client's own pending operation's response, due to messageID collision. This can cause a client application to treat a failed authentication (bind) attempt as successful. | ||||
| CVE-2026-85534 | 2 Gnome, Redhat | 3 Libsoup, Enterprise Linux, Rhel Els | 2026-11-06 | 5.9 Medium |
| A flaw was found in libsoup. When a client sends an HTTP/2 request body from a non-pollable input stream, the library can buffer more data than the current flow-control window later allows. A malicious HTTP/2 server can shrink SETTINGS_INITIAL_WINDOW_SIZE while that buffered read is still in progress. The client then copies the full buffer into a smaller DATA callback without a runtime bounds check, which can abort the process or fail the HTTP/2 session. | ||||
| CVE-2026-85518 | 1 Redhat | 3 Enterprise Linux, Hummingbird, Rhel Els | 2026-11-06 | 6.1 Medium |
| A flaw was found in OpenSCAP. When decomposing a Source DataStream (SDS) file, the application does not properly validate relative file path attributes, leading to a path traversal vulnerability. An attacker can exploit this flaw by tricking a user or automated system into decomposing a crafted datastream containing directory traversal sequences. Successful exploitation allows unauthorized file creation or modification outside the intended target directory with the permissions of the executing process. | ||||
| CVE-2026-85234 | 1 Redhat | 3 Enterprise Linux, Hummingbird, Rhel Els | 2026-11-06 | 7.5 High |
| A flaw was found in tftp-hpa. When the `in.tftpd` remap engine processes an inverse remap rule that also aborts with a non-empty custom error message, it can pass invalid match offsets to the `genmatchstring()` function. This leads to out-of-bounds read/write operations. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted request, causing the daemon to crash and resulting in a denial of service. | ||||
| CVE-2026-85150 | 2 Freedesktop, Redhat | 3 Gstreamer, Enterprise Linux, Rhel Els | 2026-11-06 | 7.5 High |
| A NULL pointer dereference flaw was found in GStreamer's RTSP support library. The vulnerability occurs while parsing an Authorization or WWW-Authenticate header that uses Digest authentication. Specially crafted whitespace placement around a parameter's terminator can cause an internal length calculation to underflow, leading to a crash of the process parsing the header. On an RTSP server this can be triggered by a remote, unauthenticated attacker sending a single malformed request when the server has authentication enabled; the same flaw can also be triggered against an RTSP client by a malicious or compromised RTSP server. Successful exploitation results in a denial of service (application crash) and has no confirmed impact on confidentiality or integrity. | ||||
| CVE-2026-84838 | 1 Redhat | 4 Enterprise Linux, Hardened Images, Hummingbird and 1 more | 2026-11-06 | 7.8 High |
| A flaw was found in rpmuncompress. This command injection vulnerability allows a local attacker to execute arbitrary commands. This occurs when rpmuncompress processes a specially crafted archive filename containing shell metacharacters, which are not properly escaped before being passed to shell command strings. Successful exploitation requires user interaction, where a user or automated workflow invokes rpmuncompress on the malicious file, leading to high impact on the confidentiality, integrity, and availability of data accessible to the invoking user. | ||||
| CVE-2026-84270 | 1 Redhat | 2 Enterprise Linux, Rhel Els | 2026-11-06 | 4.3 Medium |
| A flaw was found in the MTP backend in gvfs. When reading a file from a mounted MTP device, do_read() in gvfsbackendmtp.c trusts the data length returned by the device without limiting it to the original size requested by the client. If a malicious MTP device responds with more bytes than requested, this unrestricted length is passed directly to memcpy(). This causes the operation to read memory outside the intended boundaries. This allows an attacker who plugs in a malicious MTP device to cause a segmentation fault when a file is read and crash the gvfsd-mtp process, resulting in a denial of service. | ||||
| CVE-2026-84269 | 1 Redhat | 2 Enterprise Linux, Rhel Els | 2026-11-06 | 6.5 Medium |
| A flaw was found in the AFP backend in gvfs. When mounting a share, a malicious AFP server can cause the DSI read path to process a length that exceeds the size requested by the client. The function does not verify the server-provided length against the pre-sized reply buffer, causing the operation to access past the intended boundaries. This issue allows a malicious server to overflow a heap buffer and crash the gvfsd-afp process, resulting in a denial of service. | ||||
| CVE-2026-84267 | 1 Redhat | 2 Enterprise Linux, Rhel Els | 2026-11-06 | 4.3 Medium |
| A flaw was found in the SFTP backend in gvfs. When mounting a share, a malicious SFTP server can cause read_string() to allocate a buffer with a certain length but the function does not verify that the buffer is completely filled, leaving the remainder of the buffer containing uninitialized heap contents. If the server sends a short FXP_HANDLE reply, these uninitialized bytes are taken as the file handle. The client will then echo these uninitialized bytes back to the server on all subsequent requests using that handle. With a length of 128 bytes, this issue allows the malicious server to deterministically read uninitialized heap memory from the gvfsd-sftp process, leaking its heap base and the load address of the libgio library, resulting in a deterministic defeat of Address Space Layout Randomization (ASLR). | ||||
