| CVE-2026-50263 | 2 Redhat, X.org | 10 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 7 more | 2026-07-27 | 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-2026-50262 | 2 Redhat, X.org | 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more | 2026-07-27 | 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-2026-50264 | 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-2026-50261 | 2 Redhat, X.org | 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more | 2026-07-27 | 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 | 2026-07-27 | 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 | 2026-07-27 | 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-2026-50258 | 2 Redhat, X.org | 10 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 7 more | 2026-07-27 | 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-2026-50256 | 2 Redhat, X.org | 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more | 2026-07-27 | 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-2026-50257 | 2 Redhat, X.org | 11 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 8 more | 2026-07-27 | 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-2026-64600 | 2 Linux, Redhat | 8 Linux Kernel, Enterprise Linux, Enterprise Linux Eus and 5 more | 2026-07-24 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: xfs: resample the data fork mapping after cycling ILOCK xfs_reflink_fill_{cow_hole,delalloc} are both presented with an inode, a data fork mapping, and a cow fork mapping. Unfortunately, these two helpers cycle the ILOCK to grab a transaction, which means that the mappings are stale as soon as we reacquire the ILOCK. Currently we refresh the cow fork mapping by re-calling xfs_find_trim_cow_extent, but we don't refresh the data fork mapping beforehand, which means that the xfs_bmap_trim_cow in that function queries the refcount btree about the wrong physical blocks and returns an inaccurate value in *shared. If *shared is now false, the directio write proceeds with a stale data fork mapping. Fix this by querying the data fork mapping if the sequence counter changes across the ILOCK cycle. | ||||
| CVE-2025-10911 | 1 Redhat | 11 Discovery, Enterprise Linux, Enterprise Linux Eus and 8 more | 2026-07-23 | 5.5 Medium |
| A use-after-free vulnerability was found in libxslt while parsing xsl nodes that may lead to the dereference of expired pointers and application crash. | ||||
| CVE-2026-10649 | 2 Clusterlabs, Redhat | 10 Pacemaker, Enterprise Linux, Enterprise Linux Eus and 7 more | 2026-07-22 | 8.6 High |
| A flaw was found in Pacemaker. An unauthenticated remote attacker can exploit an integer overflow vulnerability in the remote message decompression process. By sending a specially crafted compressed remote message before authentication, an attacker can cause memory corruption, leading to a denial of service (DoS) in the CIB remote listener. This can result in the affected service crashing. | ||||
| CVE-2026-3833 | 2 Gnu, Redhat | 15 Gnutls, Discovery, Enterprise Linux and 12 more | 2026-07-22 | 6.5 Medium |
| A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of `nameConstraints` labels, specifically for `dNSName` (DNS) or `rfc822Name` (email) constraints within `excludedSubtrees` or `permittedSubtrees`. A remote attacker can exploit this by crafting a leaf certificate with casing differences in the Subject Alternative Name (SAN), leading to a policy bypass where a certificate that should be rejected is instead accepted. This could result in unauthorized access or information disclosure. | ||||
| CVE-2026-42010 | 2 Gnu, Redhat | 15 Gnutls, Ai Inference Server, Discovery and 12 more | 2026-07-22 | 7.1 High |
| A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass. This vulnerability allows an attacker to gain unauthorized access by circumventing the authentication process. | ||||
| CVE-2026-42009 | 2 Gnu, Redhat | 26 Gnutls, Ai Inference Server, Discovery and 23 more | 2026-07-22 | 7.5 High |
| A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security (DTLS) packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. This could lead to unstable packet ordering or undefined behavior, resulting in a denial of service. | ||||
| CVE-2023-3390 | 3 Linux, Netapp, Redhat | 12 Linux Kernel, H300s, H410c and 9 more | 2026-07-22 | 7.8 High |
| A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nf_tables_api.c. Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local attacker with user access to cause a privilege escalation issue. We recommend upgrading past commit 1240eb93f0616b21c675416516ff3d74798fdc97 | ||||
| CVE-2026-42013 | 2 Gnu, Redhat | 14 Gnutls, Discovery, Enterprise Linux and 11 more | 2026-07-20 | 8.2 High |
| A flaw was found in gnutls. When validating certificates, an oversized Subject Alternative Name (SAN) could cause the validation process to incorrectly fall back to checking the Common Name (CN) field. This could allow a remote attacker to bypass proper certificate validation, potentially leading to spoofing or man-in-the-middle attacks. | ||||
| CVE-2026-42012 | 2 Gnu, Redhat | 14 Gnutls, Discovery, Enterprise Linux and 11 more | 2026-07-20 | 7.1 High |
| A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted certificate that contains Uniform Resource Identifier (URI) or Service (SRV) Subject Alternative Names (SANs). This could cause the certificate validation process to incorrectly fall back to checking DNS hostnames against the Common Name (CN), potentially allowing the attacker to spoof legitimate services or intercept sensitive information. | ||||
| CVE-2026-42011 | 1 Redhat | 13 Discovery, Enterprise Linux, Enterprise Linux Eus and 10 more | 2026-07-20 | 7.4 High |
| A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities (CAs) only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate validation. This bypass could lead to the acceptance of invalid certificates, potentially enabling spoofing or man-in-the-middle attacks against affected systems. | ||||
| CVE-2026-5260 | 2 Gnu, Redhat | 14 Gnutls, Discovery, Enterprise Linux and 11 more | 2026-07-20 | 8.2 High |
| A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS#11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information disclosure. | ||||
