| CVE-2025-26601 | 3 Redhat, Tigervnc, X.org | 4 Enterprise Linux, Tigervnc, X Server and 1 more | 2025-05-16 | 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 | 2025-05-16 | 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 | 2025-05-13 | 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 | 2025-05-13 | 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 | 2025-05-13 | 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 | 2025-05-13 | 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 | 2025-05-13 | 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 | 2025-05-13 | 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-2022-46343 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2025-04-22 | N/A | 8.8 HIGH |
| A vulnerability was found in X.Org. This security flaw occurs because the handler for the ScreenSaverSetAttributes request may write to memory after it has been freed. This issue can lead to local privileges elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions. | |||||
| CVE-2022-46342 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2025-04-22 | N/A | 8.8 HIGH |
| A vulnerability was found in X.Org. This security flaw occurs because the handler for the XvdiSelectVideoNotify request may write to memory after it has been freed. This issue can lead to local privileges elevation on systems where the X se | |||||
| CVE-2022-46341 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2025-04-22 | N/A | 8.8 HIGH |
| A vulnerability was found in X.Org. This security flaw occurs because the handler for the XIPassiveUngrab request accesses out-of-bounds memory when invoked with a high keycode or button code. This issue can lead to local privileges elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions. | |||||
| CVE-2022-46340 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2025-04-22 | N/A | 8.8 HIGH |
| A vulnerability was found in X.Org. This security flaw occurs becuase the swap handler for the XTestFakeInput request of the XTest extension may corrupt the stack if GenericEvents with lengths larger than 32 bytes are sent through a the XTestFakeInput request. This issue can lead to local privileges elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions. This issue does not affect systems where client and server use the same byte order. | |||||
| CVE-2016-10164 | 1 X.org | 1 Libxpm | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
| Multiple integer overflows in libXpm before 3.5.12, when a program requests parsing XPM extensions on a 64-bit platform, allow remote attackers to cause a denial of service (out-of-bounds write) or execute arbitrary code via (1) the number of extensions or (2) their concatenated length in a crafted XPM file, which triggers a heap-based buffer overflow. | |||||
| CVE-2017-13721 | 2 Debian, X.org | 2 Debian Linux, Xorg-server | 2025-04-20 | 1.9 LOW | 4.7 MEDIUM |
| In X.Org Server (aka xserver and xorg-server) before 1.19.4, an attacker authenticated to an X server with the X shared memory extension enabled can cause aborts of the X server or replace shared memory segments of other X clients in the same session. | |||||
| CVE-2017-10971 | 1 X.org | 1 Xorg-server | 2025-04-20 | 6.5 MEDIUM | 8.8 HIGH |
| In the X.Org X server before 2017-06-19, a user authenticated to an X Session could crash or execute code in the context of the X Server by exploiting a stack overflow in the endianness conversion of X Events. | |||||
| CVE-2017-13722 | 1 X.org | 1 Libxfont | 2025-04-20 | 3.6 LOW | 7.1 HIGH |
| In the pcfGetProperties function in bitmap/pcfread.c in libXfont through 1.5.2 and 2.x before 2.0.2, a missing boundary check (for PCF files) could be used by local attackers authenticated to an Xserver for a buffer over-read, for information disclosure or a crash of the X server. | |||||
| CVE-2017-13723 | 2 Debian, X.org | 2 Debian Linux, Xorg-server | 2025-04-20 | 4.6 MEDIUM | 7.8 HIGH |
| In X.Org Server (aka xserver and xorg-server) before 1.19.4, a local attacker authenticated to the X server could overflow a global buffer, causing crashes of the X server or potentially other problems by injecting large or malformed XKB related atoms and accessing them via xkbcomp. | |||||
| CVE-2017-10972 | 1 X.org | 1 Xorg-server | 2025-04-20 | 4.0 MEDIUM | 6.5 MEDIUM |
| Uninitialized data in endianness conversion in the XEvent handling of the X.Org X Server before 2017-06-19 allowed authenticated malicious users to access potentially privileged data from the X server. | |||||
| CVE-2017-13720 | 1 X.org | 1 Libxfont | 2025-04-20 | 3.6 LOW | 7.1 HIGH |
| In the PatternMatch function in fontfile/fontdir.c in libXfont through 1.5.2 and 2.x before 2.0.2, an attacker with access to an X connection can cause a buffer over-read during pattern matching of fonts, leading to information disclosure or a crash (denial of service). This occurs because '\0' characters are incorrectly skipped in situations involving ? characters. | |||||
| CVE-2022-4283 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Enterprise Linux and 1 more | 2025-04-14 | N/A | 7.8 HIGH |
| A vulnerability was found in X.Org. This security flaw occurs because the XkbCopyNames function left a dangling pointer to freed memory, resulting in out-of-bounds memory access on subsequent XkbGetKbdByName requests.. This issue can lead to local privileges elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions. | |||||
