CVE-2025-26601 (GCVE-0-2025-26601)
Vulnerability from nvd – Published: 2025-02-25 15:55 – Updated: 2025-11-06 21:09
VLAI?
Summary
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.
Severity ?
7.8 (High)
CWE
- CWE-416 - Use After Free
Assigner

CVE-2025-26599 (GCVE-0-2025-26599)

Summary
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.
Severity ?
7.8 (High)
CWE
- CWE-824 - Access of Uninitialized Pointer

CVE-2025-26598 (GCVE-0-2025-26598)
Vulnerability from nvd – Published: 2025-02-25 15:54 – Updated: 2025-11-06 21:09
VLAI?
Summary
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.
Severity ?
7.8 (High)
CWE
- CWE-787 - Out-of-bounds Write

CVE-2025-26597 (GCVE-0-2025-26597)
Vulnerability from nvd – Published: 2025-02-25 15:54 – Updated: 2025-11-06 21:09
VLAI?
Summary
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.
Severity ?
7.8 (High)
CWE
- CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer

CVE-2025-26601 (GCVE-0-2025-26601)
Vulnerability from cvelistv5 – Published: 2025-02-25 15:55 – Updated: 2025-11-06 21:09
VLAI?
Summary
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.
Severity ?
7.8 (High)
CWE
- CWE-416 - Use After Free

CVE-2025-26599 (GCVE-0-2025-26599)
Vulnerability from cvelistv5 – Published: 2025-02-25 15:55 – Updated: 2025-11-06 21:09
VLAI?
Summary
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.
Severity ?
7.8 (High)
CWE
- CWE-824 - Access of Uninitialized Pointer
Assigner

CVE-2025-26598 (GCVE-0-2025-26598)
Vulnerability from cvelistv5 – Published: 2025-02-25 15:54 – Updated: 2025-11-06 21:09
VLAI?
Summary
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.
Severity ?
7.8 (High)
CWE
- CWE-787 - Out-of-bounds Write

CVE-2025-26597 (GCVE-0-2025-26597)
Vulnerability from cvelistv5 – Published: 2025-02-25 15:54 – Updated: 2025-11-06 21:09
VLAI?
Summary
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.
Severity ?
7.8 (High)
CWE
- CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer

Vulnerability from fkie_nvd - Published: 2025-02-25 16:15 - Updated: 2025-11-03 22:18
Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary
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.

Summary
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.

Vulnerability from fkie_nvd - Published: 2025-02-25 16:15 - Updated: 2025-11-03 22:18
Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
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.

Summary
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.

FKIE_CVE-2025-26595
Vulnerability from fkie_nvd - Published: 2025-02-25 16:15 - Updated: 2025-11-03 22:18
Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary
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.

Summary
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.

Vulnerability from fkie_nvd - Published: 2025-02-25 16:15 - Updated: 2025-11-03 22:18

Summary
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.
