04 Mar 2025 — Android apps can load web pages using the Custom Tabs feature. This feature supports a transition animation that could have been used to trick a user into granting sensitive permissions by hiding what the user was actually clicking. This vulnerability affects Firefox < 136. • https://bugzilla.mozilla.org/show_bug.cgi?id=1928334 • CWE-359: Exposure of Private Personal Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2025-26601
25 Feb 2025 — 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. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server... • https://access.redhat.com/security/cve/CVE-2025-26601 • CWE-416: Use After Free •

25 Feb 2025 — 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. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

https://notcve.org/view.php?id=CVE-2025-26599
25 Feb 2025 — 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. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. An attacker must first obta... • https://access.redhat.com/security/cve/CVE-2025-26599 • CWE-824: Access of Uninitialized Pointer •

https://notcve.org/view.php?id=CVE-2025-26598
25 Feb 2025 — 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. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. An attacker must first obtain the abilit... • https://access.redhat.com/security/cve/CVE-2025-26598 • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2025-26597
25 Feb 2025 — 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.

25 Feb 2025 — 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. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the XkbSizeKeySyms function.

25 Feb 2025 — 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.

25 Feb 2025 — 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.

https://notcve.org/view.php?id=CVE-2025-26465
18 Feb 2025 — A vulnerability was found in OpenSSH when the VerifyHostKeyDNS option is enabled. A machine-in-the-middle attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how OpenSSH mishandles error codes in specific conditions when verifying the host key. For an attack to be considered successful, the attacker needs to manage to exhaust the client's memory resource first, turning the attack complexity high. It was discovered that the OpenSSH client incorrectly handled ... • https://github.com/rxerium/CVE-2025-26465 • CWE-390: Detection of Error Condition Without Action •
