CVE-2026-86845 1 Redhat 3 Enterprise Linux, Openshift, Openstack 2026-11-06 6.5 Medium
A flaw was found in DPDK lib/vhost vhost-crypto. Session cleanup can leave a stale cached session pointer, and the data path does not check the session type before attaching it, leading to use-after-free or type confusion in the host vhost-crypto backend.
CVE-2026-86566 3 Dpdk, Red Hat, Redhat 6 Dpdk, Enterprise Linux, Enterprise Linux and 3 more 2026-11-06 6.5 Medium
A flaw was found in DPDK lib/vhost. A guest with runt RX descriptors can underflow the copy length in vhost enqueue, causing a denial of service in a shared vhost backend such as OVS-DPDK.
CVE-2026-86561 3 Dpdk, Red Hat, Redhat 8 Dpdk, Enterprise Linux, Enterprise Linux and 5 more 2026-11-06 6.5 Medium
A flaw was found in DPDK lib/vhost. Memory size is not adequately validated before mmap during vhost memory-region setup, which can lead to a host crash or memory corruption.
CVE-2026-86469 1 Redhat 6 Enterprise Linux, Hardened Images, Hummingbird and 3 more 2026-11-06 5.3 Medium
A flaw was found in GLib2. When g_file_replace() is used with G_FILE_CREATE_REPLACE_DESTINATION and creating the .goutputstream-XXXXXX temporary file fails, the library unlinks the destination and recreates it without exclusive creation or symlink protection. A local attacker who can write to the destination directory can win that race and redirect the write to another file.
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-2026-85977 2 Libtirpc Project, Redhat 7 Libtirpc, Enterprise Linux, Hardened Images and 4 more 2026-11-06 5.3 Medium
A flaw was found in libtirpc. A remote attacker can exploit this vulnerability by sending specially crafted PMAPPROC_DUMP replies to a client application that uses the pmap_getmaps() function against an attacker-controlled host. This unbounded decoding can lead to excessive memory and CPU allocation, causing the client process to experience a Denial of Service (DoS) due to resource exhaustion.
CVE-2026-85769 1 Redhat 1 Enterprise Linux 2026-11-06 6.5 Medium
A flaw was found in libtpms, a library that provides software TPM 2.0 emulation. When restoring TPM 2.0 state (for example during a virtual machine's power-on or state/migration restore), a malformed state blob can supply an oversized skip-block length that is not validated against the remaining size of the input buffer. This can drive an internal size counter negative, which bypasses a subsequent bounds check due to an unsafe signed-to-unsigned conversion, causing the parser to read memory outside the bounds of the heap buffer holding the state data. Successful exploitation can crash the process hosting libtpms (such as swtpm), resulting in a denial of service of the emulated TPM device and the virtual machine that depends on it. No data corruption or information disclosure was confirmed.
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-2026-85231 1 Redhat 4 Enterprise Linux, Hummingbird, Openshift and 1 more 2026-11-06 6.5 Medium
A flaw was found in libtirpc. An authenticated remote attacker could exploit this vulnerability by sending oversized wrapped data requests to an RPC (Remote Procedure Call) service configured with RPCSEC_GSS (Remote Procedure Call Security-Generic Security Service) integrity or privacy. This can lead to unbounded memory allocation, resulting in a Denial of Service (DoS) by exhausting system resources and causing the service to become unstable or terminate.
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-2026-85013 1 Redhat 3 Enterprise Linux, Hummingbird, Rhel Els 2026-11-06 7.3 High
A flaw was found in environment-modules. A local attacker can exploit this vulnerability by placing a maliciously named modulefile in a location visible to the victim's `MODULEPATH`. When the victim uses Bash completion for `module` or `ml` commands, the malicious module name, containing shell metacharacters, is evaluated as a command. This can lead to arbitrary command execution in the completing user's shell, impacting their confidentiality, integrity, and availability.
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-2026-84837 1 Redhat 4 Enterprise Linux, Hardened Images, Hummingbird and 1 more 2026-11-06 7.8 High
A flaw was found in rpm. An attacker can exploit a command injection vulnerability by influencing the path or filename of a tarball processed by `rpmbuild -t*` to include shell metacharacters. This is particularly relevant in automated build or continuous integration (CI) workflows that ingest externally supplied artifact names. Successful exploitation allows for arbitrary command execution with the privileges of the build user, which could lead to information disclosure or disruption of the build environment.
CVE-2026-84828 1 Redhat 5 Enterprise Linux, Openshift, Openshift Container Platform and 2 more 2026-11-06 6.5 Medium
A flaw was found in PCS (Pacemaker Configuration System). A local attacker with membership in the 'haclient' group can exploit the 'pcs host auth --token' command to read the contents of arbitrary files on the filesystem, provided the files are shorter than 256 bytes. The file contents are read with root privileges by the pcsd daemon and can be exfiltrated by the attacker through subsequent cluster node communication. This allows disclosure of sensitive data such as API keys, tokens, or configuration secrets that would otherwise be inaccessible to the attacker.
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).
CVE-2026-84233 1 Redhat 4 Enterprise Linux, Hardened Images, Hummingbird and 1 more 2026-11-06 7 High
A flaw was found in rpm. A local attacker could supply a specially crafted `.gem` filename containing RPM macro syntax. When a user or automated workflow invokes `rpmuncompress -x` on this file, the macro expansion occurs during command construction. This allows the attacker to execute arbitrary commands with the privileges of the invoking account, leading to a compromise of confidentiality, integrity, and availability.
