CVE-2025-47711 2 Nbdkit Project, Redhat 3 Nbdkit, Enterprise Linux, Enterprise Linux Advanced Virtualization 2026-06-30 N/A 6.5 MEDIUM
There's a flaw in the nbdkit server when handling responses from its plugins regarding the status of data blocks. If a client makes a specific request for a very large data range, and a plugin responds with an even larger single block, the nbdkit server can encounter a critical internal error, leading to a denial-of-service.
CVE-2025-46400 2 Fig2dev Project, Redhat 2 Fig2dev, Enterprise Linux 2026-06-30 N/A 5.5 MEDIUM
In xfig diagramming tool, a segmentation fault while running fig2dev allows an attacker to availability via local input manipulation via read_arcobject function.
CVE-2025-46399 2 Fig2dev Project, Redhat 2 Fig2dev, Enterprise Linux 2026-06-30 N/A 5.5 MEDIUM
A flaw was found in fig2dev. This vulnerability allows availability via local input manipulation via genge_itp_spline function.
CVE-2025-46398 2 Fig2dev Project, Redhat 2 Fig2dev, Enterprise Linux 2026-06-30 N/A 5.5 MEDIUM
In xfig diagramming tool, a stack-overflow while running fig2dev allows memory corruption via local input manipulation via read_objects function.
CVE-2025-46397 2 Fig2dev Project, Redhat 2 Fig2dev, Enterprise Linux 2026-06-30 N/A 7.8 HIGH
A flaw was found in xfig. This vulnerability allows possible code execution via local input manipulation via bezier_spline function.
CVE-2024-10041 2 Linux-pam, Redhat 2 Linux-pam, Enterprise Linux 2026-06-30 N/A 4.7 MEDIUM
A vulnerability was found in PAM. The secret information is stored in memory, where the attacker can trigger the victim program to execute by sending characters to its standard input (stdin). As this occurs, the attacker can train the branch predictor to execute an ROP chain speculatively. This flaw could result in leaked passwords, such as those found in /etc/shadow while performing authentications.
CVE-2025-3891 3 Apache, Debian, Redhat 3 Http Server, Debian Linux, Enterprise Linux 2026-06-29 N/A 7.5 HIGH
A flaw was found in the mod_auth_openidc module for Apache httpd. This flaw allows a remote, unauthenticated attacker to trigger a denial of service by sending an empty POST request when the OIDCPreservePost directive is enabled. The server crashes consistently, affecting availability.
CVE-2025-3155 3 Debian, Gnome, Redhat 21 Debian Linux, Yelp, Codeready Linux Builder and 18 more 2026-06-29 N/A 7.4 HIGH
A flaw was found in Yelp. The Gnome user help application allows the help document to execute arbitrary scripts. This vulnerability allows malicious users to input help documents, which may exfiltrate user files to an external environment.
CVE-2025-26601 3 Redhat, Tigervnc, X.org 4 Enterprise Linux, Tigervnc, X Server and 1 more 2026-06-29 N/A 7.8 HIGH
A use-after-free flaw was found in X.Org and Xwayland. When changing an alarm, the values of the change mask are evaluated one after the other, changing the trigger values as requested, and eventually, SyncInitTrigger() is called. If one of the changes triggers an error, the function will return early, not adding the new sync object, possibly causing a use-after-free when the alarm eventually triggers.
CVE-2025-26600 3 Redhat, Tigervnc, X.org 4 Enterprise Linux, Tigervnc, X Server and 1 more 2026-06-29 N/A 7.8 HIGH
A use-after-free flaw was found in X.Org and Xwayland. When a device is removed while still frozen, the events queued for that device remain while the device is freed. Replaying the events will cause a use-after-free.
CVE-2025-26599 3 Redhat, Tigervnc, X.org 4 Enterprise Linux, Tigervnc, X Server and 1 more 2026-06-29 N/A 7.8 HIGH
An access to an uninitialized pointer flaw was found in X.Org and Xwayland. The function compCheckRedirect() may fail if it cannot allocate the backing pixmap. In that case, compRedirectWindow() will return a BadAlloc error without validating the window tree marked just before, which leaves the validated data partly initialized and the use of an uninitialized pointer later.
CVE-2025-26598 3 Redhat, Tigervnc, X.org 4 Enterprise Linux, Tigervnc, X Server and 1 more 2026-06-29 N/A 7.8 HIGH
An out-of-bounds write flaw was found in X.Org and Xwayland. The function GetBarrierDevice() searches for the pointer device based on its device ID and returns the matching value, or supposedly NULL, if no match was found. However, the code will return the last element of the list if no matching device ID is found, which can lead to out-of-bounds memory access.
CVE-2025-26597 3 Redhat, Tigervnc, X.org 4 Enterprise Linux, Tigervnc, X Server and 1 more 2026-06-29 N/A 7.8 HIGH
A buffer overflow flaw was found in X.Org and Xwayland. If XkbChangeTypesOfKey() is called with a 0 group, it will resize the key symbols table to 0 but leave the key actions unchanged. If the same function is later called with a non-zero value of groups, this will cause a buffer overflow because the key actions are of the wrong size.
CVE-2025-26596 3 Redhat, Tigervnc, X.org 4 Enterprise Linux, Tigervnc, X Server and 1 more 2026-06-29 N/A 7.8 HIGH
A heap overflow flaw was found in X.Org and Xwayland. The computation of the length in XkbSizeKeySyms() differs from what is written in XkbWriteKeySyms(), which may lead to a heap-based buffer overflow.
CVE-2025-26595 3 Redhat, Tigervnc, X.org 4 Enterprise Linux, Tigervnc, X Server and 1 more 2026-06-29 N/A 7.8 HIGH
A buffer overflow flaw was found in X.Org and Xwayland. The code in XkbVModMaskText() allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and would copy the data regardless of the size.
CVE-2025-26594 3 Redhat, Tigervnc, X.org 4 Enterprise Linux, Tigervnc, X Server and 1 more 2026-06-29 N/A 7.8 HIGH
A use-after-free flaw was found in X.Org and Xwayland. The root cursor is referenced in the X server as a global variable. If a client frees the root cursor, the internal reference points to freed memory and causes a use-after-free.
CVE-2026-12528 1 Redhat 3 389 Directory Server, Directory Server, Enterprise Linux 2026-06-28 N/A 5.4 MEDIUM
A flaw was found in 389 Directory Server in the __aclp__normalize_acltxt() function of aclparse.c. A malformed ACI (Access Control Instruction) string can trigger heap-buffer-overflow writes and reads during ACI parsing. The function fails to validate that the ACI keyword has sufficient length after whitespace stripping, leading to a 1-byte out-of-bounds write and subsequent out-of-bounds reads. An authenticated user with write access to the aci attribute could send a crafted ACI value to silently corrupt heap memory in the directory server process.
CVE-2023-40547 1 Redhat 2 Enterprise Linux, Shim 2026-06-26 N/A 8.3 HIGH
A remote code execution vulnerability was found in Shim. The Shim boot support trusts attacker-controlled values when parsing an HTTP response. This flaw allows an attacker to craft a specific malicious HTTP request, leading to a completely controlled out-of-bounds write primitive and complete system compromise. This flaw is only exploitable during the early boot phase, an attacker needs to perform a Man-in-the-Middle or compromise the boot server to be able to exploit this vulnerability successfully.
CVE-2023-39328 2 Redhat, Uclouvain 2 Enterprise Linux, Openjpeg 2026-06-26 N/A 5.5 MEDIUM
A vulnerability was found in OpenJPEG similar to CVE-2019-6988. This flaw allows an attacker to bypass existing protections and cause an application crash through a maliciously crafted file.
CVE-2025-31181 2 Gnuplot, Redhat 2 Gnuplot, Enterprise Linux 2026-06-26 N/A 6.2 MEDIUM
A flaw was found in gnuplot. The X11_graphics() function may lead to a segmentation fault and cause a system crash.
