In jQuery versions greater than or equal to 1.0.3 and before 3.5.0, passing HTML containing <option> elements from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code. This problem is patched in jQuery 3.5.0.
CVE-2025-7345 1 Redhat 7 Enterprise Linux, Rhel Aus, Rhel E4s and 4 more 2025-11-07 7.5 High
A flaw exists in gdk‑pixbuf within the gdk_pixbuf__jpeg_image_load_increment function (io-jpeg.c) and in glib’s g_base64_encode_step (glib/gbase64.c). When processing maliciously crafted JPEG images, a heap buffer overflow can occur during Base64 encoding, allowing out-of-bounds reads from heap memory, potentially causing application crashes or arbitrary code execution.
CVE-2024-8445 1 Redhat 3 Directory Server, Enterprise Linux, Rhel Els 2025-11-06 5.7 Medium
The fix for CVE-2024-2199 in 389-ds-base was insufficient to cover all scenarios. In certain product versions, an authenticated user may cause a server crash while modifying `userPassword` using malformed input.
CVE-2025-48798 1 Redhat 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more 2025-11-06 7.3 High
A flaw was found in GIMP when processing XCF image files. If a user opens one of these image files that has been specially crafted by an attacker, GIMP can be tricked into making serious memory errors, potentially leading to crashes and causing use-after-free issues.
CVE-2025-48797 1 Redhat 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more 2025-11-06 7.3 High
A flaw was found in GIMP when processing certain TGA image files. If a user opens one of these image files that has been specially crafted by an attacker, GIMP can be tricked into making serious memory errors, potentially leading to crashes and causing a heap buffer overflow.
CVE-2025-26601 3 Redhat, Tigervnc, X.org 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more 2025-11-06 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 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more 2025-11-06 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 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more 2025-11-06 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 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more 2025-11-06 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 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more 2025-11-06 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 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more 2025-11-06 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 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more 2025-11-06 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 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more 2025-11-06 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-2024-21886 2 Redhat, Xorg 8 Enterprise Linux, Rhel Aus, Rhel E4s and 5 more 2025-11-06 7.8 High
A heap buffer overflow flaw was found in the DisableDevice function in the X.Org server. This issue may lead to an application crash or, in some circumstances, remote code execution in SSH X11 forwarding environments.
CVE-2024-21885 1 Redhat 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more 2025-11-06 7.8 High
A flaw was found in X.Org server. In the XISendDeviceHierarchyEvent function, it is possible to exceed the allocated array length when certain new device IDs are added to the xXIHierarchyInfo struct. This can trigger a heap buffer overflow condition, which may lead to an application crash or remote code execution in SSH X11 forwarding environments.
CVE-2024-0229 3 Fedoraproject, Redhat, X.org 13 Fedora, Enterprise Linux, Enterprise Linux Aus and 10 more 2025-11-06 7.8 High
An out-of-bounds memory access flaw was found in the X.Org server. This issue can be triggered when a device frozen by a sync grab is reattached to a different master device. This issue may lead to an application crash, local privilege escalation (if the server runs with extended privileges), or remote code execution in SSH X11 forwarding environments.
CVE-2023-5367 4 Debian, Fedoraproject, Redhat and 1 more 17 Debian Linux, Fedora, Enterprise Linux and 14 more 2025-11-06 7.8 High
A out-of-bounds write flaw was found in the xorg-x11-server. This issue occurs due to an incorrect calculation of a buffer offset when copying data stored in the heap in the XIChangeDeviceProperty function in Xi/xiproperty.c and in RRChangeOutputProperty function in randr/rrproperty.c, allowing for possible escalation of privileges or denial of service.
CVE-2021-4034 7 Canonical, Oracle, Polkit Project and 4 more 37 Ubuntu Linux, Http Server, Zfs Storage Appliance Kit and 34 more 2025-11-06 7.8 High
A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine.
CVE-2024-36971 3 Debian, Linux, Redhat 9 Debian Linux, Linux Kernel, Enterprise Linux and 6 more 2025-11-05 7.8 High
In the Linux kernel, the following vulnerability has been resolved: net: fix __dst_negative_advice() race __dst_negative_advice() does not enforce proper RCU rules when sk->dst_cache must be cleared, leading to possible UAF. RCU rules are that we must first clear sk->sk_dst_cache, then call dst_release(old_dst). Note that sk_dst_reset(sk) is implementing this protocol correctly, while __dst_negative_advice() uses the wrong order. Given that ip6_negative_advice() has special logic against RTF_CACHE, this means each of the three ->negative_advice() existing methods must perform the sk_dst_reset() themselves. Note the check against NULL dst is centralized in __dst_negative_advice(), there is no need to duplicate it in various callbacks. Many thanks to Clement Lecigne for tracking this issue. This old bug became visible after the blamed commit, using UDP sockets.
