| CVE-2026-58016 | 2 Gnome, Redhat | 13 Glib, Discovery, Enterprise Linux and 10 more | 2026-08-07 | 7.5 High |
| A flaw was found in GLib. A state confusion issue exists in g_dbus_node_info_new_for_xml() in the gio/gdbusintrospection.c file when processing malformed D-Bus introspection XML, specifically with a `node` element nested within other elements like `method`, `signal`, `property` or `arg`. This issue can cause an unsigned integer overflow and lead to an out-of-bounds read, resulting in a denial of service. | ||||
| CVE-2026-50257 | 2 Redhat, X.org | 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more | 2026-08-04 | 7.8 High |
| A use-after-free flaw was found in the X.Org X server and Xwayland in miSyncDestroyFence(). A client that sets up multiple fence triggers can trigger a use-after-free function pointer call. An attacker would connect to the X server to set up a fence and await that fence, then a second X connection destroys the fence, causing the use-after-free. This may be used to crash the server, or for privilege escalation if the X server runs as root. | ||||
| CVE-2026-50262 | 2 Redhat, X.org | 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more | 2026-08-04 | 5.5 Medium |
| An out-of-bounds read flaw was found in the X.Org X server and Xwayland in __glXDisp_ChangeDrawableAttributes(). A wrong size validation check can read a client-controlled number of bytes, exceeding the request buffer, leading to information disclosure. A write path also exists but requires byte-swapped clients which is disabled by default. | ||||
| CVE-2026-50258 | 2 Redhat, X.org | 10 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 7 more | 2026-08-04 | 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-2026-50261 | 2 Redhat, X.org | 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more | 2026-08-04 | 7.8 High |
| A use-after-free flaw was found in the X.Org X server and Xwayland in SyncChangeCounter(). A client that sets up multiple SyncCounters can trigger a use-after-free when destroying those counters via a second client connection while changing those counters. This may be used to crash the server, or for privilege escalation if the X server runs as root. | ||||
| CVE-2026-50260 | 2 Redhat, X.org | 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more | 2026-08-04 | 7.8 High |
| A use-after-free flaw was found in the X.Org X server and Xwayland in FreeCounter(). A client that sets up multiple SyncCounters and awaits on those triggers can trigger a use-after-free when destroying those counters via a second client connection. 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 | 2026-08-04 | 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-2026-50263 | 2 Redhat, X.org | 10 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 7 more | 2026-08-04 | 5.5 Medium |
| A use-after-free flaw was found in the X.Org X server and Xwayland in CreateSaverWindow(). A client can trigger a use-after-free read after changing window attributes and forcing the screen saver, leading to information disclosure. | ||||
| CVE-2026-50256 | 2 Redhat, X.org | 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more | 2026-08-04 | 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-2026-48864 | 2 Opensuse, Redhat | 20 Libsolv, Discovery, Enterprise Linux and 17 more | 2026-08-04 | 7.8 High |
| A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within `.solv` files due to insufficient input validation. An attacker can provide a specially crafted `.solv` file, which, when processed by a vulnerable application, can lead to out-of-bounds memory access. This could result in information disclosure, alteration of program execution, or a denial of service. | ||||
| CVE-2026-14476 | 2 Redhat, Sssd | 11 Enterprise Linux, Enterprise Linux Eus, Openshift and 8 more | 2026-08-04 | 8 High |
| A path traversal flaw was found in SSSD's AD GPO provider. The ad_gpo_extract_smb_components() function does not sanitize .. sequences in the gPCFileSysPath LDAP attribute, allowing an attacker with AD GPO management access to write files outside the GPO cache directory as root. On default RHEL configurations with SELinux enforcing, this can be used to inject Kerberos configuration leading to authentication bypass. | ||||
| CVE-2026-14474 | 1 Redhat | 9 Enterprise Linux, Enterprise Linux Eus, Openshift and 6 more | 2026-08-04 | 8.8 High |
| A flaw was found in SSSD's LDAP sudo provider. When the ldap_sudo_search_base option is not explicitly configured, SSSD searches the entire LDAP directory tree for sudoRole objects. An authenticated attacker with write access to any subtree can inject a sudoRole object granting root-level sudo privileges on all SSSD-enrolled hosts. | ||||
| CVE-2026-52722 | 2 Gstreamer Project, Redhat | 9 Gstreamer Plugin, Enterprise Linux, Enterprise Linux Eus and 6 more | 2026-08-03 | 7.1 High |
| A signed integer overflow vulnerability was found in GStreamer's VMnc decoder. A crafted VMnc stream with large cursor dimensions can overflow signed integer payload-size arithmetic, bypassing a length check and leading to out-of-bounds reads. A remote attacker could trick a user into opening a specially crafted VMnc file, potentially causing a crash or information disclosure. | ||||
| CVE-2026-52720 | 2 Gstreamer Project, Redhat | 9 Gstreamer Plugin, Enterprise Linux, Enterprise Linux Eus and 6 more | 2026-08-03 | 8.8 High |
| A heap buffer overflow vulnerability was found in GStreamer's librfb (RFB/VNC client). The rectangle bounds check incorrectly validates area rather than individual dimensions, allowing a malicious VNC server to send a rectangle that extends beyond the framebuffer. A remote attacker could set up a malicious VNC server and trick a user into connecting, resulting in an out-of-bounds heap write that could lead to code execution or a crash. | ||||
| CVE-2026-53705 | 2 Gstreamer Project, Redhat | 9 Gstreamer Plugin, Enterprise Linux, Enterprise Linux Eus and 6 more | 2026-08-03 | 7.6 High |
| A flaw was found in GStreamer's WavPack audio decoder in gst-plugins-good. When processing a specially crafted WavPack file, an integer overflow in the buffer size calculation (4 * block_samples * channels) in gst_wavpack_dec_handle_frame() causes a very small heap allocation. The WavPack library then writes decoded audio samples far beyond the allocated buffer, resulting in heap memory corruption. This affects both 32-bit and 64-bit systems since the arithmetic is performed in 32-bit integers before promotion to the allocation size type. A remote attacker could use this flaw to crash an application or potentially execute arbitrary code by convincing a user to open a malicious WavPack audio file. | ||||
| CVE-2025-14087 | 2 Gnome, Redhat | 15 Glib, Ai Inference Server, Discovery and 12 more | 2026-08-03 | 5.6 Medium |
| A flaw was found in GLib (Gnome Lib). This vulnerability allows a remote attacker to cause heap corruption, leading to a denial of service or potential code execution via a buffer-underflow in the GVariant parser when processing maliciously crafted input strings. | ||||
| CVE-2026-54229 | 1 Redhat | 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more | 2026-07-31 | 7 High |
| A race condition was found in the abrt-dbus D-Bus service's ChownProblemDir method. ChownProblemDir opens the dump directory with DD_OPEN_READONLY and calls dd_chown to change ownership of all files to the caller's uid, succeeding even while post-create event handlers hold a write lock. This allows an attacker to gain filesystem-level control of the dump directory while privileged event scripts are still running. | ||||
| CVE-2026-54228 | 1 Redhat | 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more | 2026-07-31 | 7.8 High |
| A time-of-check time-of-use (TOCTOU) race condition was found in the abrt-dbus D-Bus service's SetElement method. Between dump directory creation and post-create event execution, any local user can call SetElement to write arbitrary text files into the root-owned dump directory, bypassing package validation and allowing crashes of unpackaged binaries to survive post-create processing. | ||||
| CVE-2026-50264 | 2 Redhat, X.org | 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more | 2026-07-27 | 7.8 High |
| An out-of-bounds write flaw was found in the X.Org X server and Xwayland in DRIGetBuffers/DRIGetBuffersWithFormat. A client that requests multiple DRI2BufferBackLeft attachments and one DRI2BufferFrontLeft can trigger an out-of-bounds heap write. This may be used to crash the server, or for privilege escalation if the X server runs as root. | ||||
| CVE-2026-42015 | 1 Redhat | 14 Discovery, Enterprise Linux, Enterprise Linux Eus and 11 more | 2026-07-22 | 5.3 Medium |
| A flaw was found in gnutls. An off-by-one error exists in the PKCS#12 bag element bounds check. This vulnerability allows an remote attacker to write past the internal array of a PKCS#12 bag when appending to a bag that already contains 32 elements. This memory corruption could lead to a denial of service (DoS) or potentially other unspecified impacts. | ||||
