CVE-2025-26601 3 Redhat, Tigervnc, X.org 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more 2025-11-03 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 2025-11-03 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 2025-11-03 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 2025-11-03 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 2025-11-03 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 2025-11-03 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 2025-11-03 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 2025-11-03 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-2025-24855 2 Redhat, Xmlsoft 8 Enterprise Linux, Openshift, Rhel Aus and 5 more 2025-11-03 7.8 High
numbers.c in libxslt before 1.1.43 has a use-after-free because, in nested XPath evaluations, an XPath context node can be modified but never restored. This is related to xsltNumberFormatGetValue, xsltEvalXPathPredicate, xsltEvalXPathStringNs, and xsltComputeSortResultInternal.
CVE-2025-6430 2 Mozilla, Redhat 8 Firefox, Firefox Esr, Enterprise Linux and 5 more 2025-11-03 6.1 Medium
When a file download is specified via the `Content-Disposition` header, that directive would be ignored if the file was included via a `&lt;embed&gt;` or `&lt;object&gt;` tag, potentially making a website vulnerable to a cross-site scripting attack. This vulnerability affects Firefox < 140, Firefox ESR < 128.12, Thunderbird < 140, and Thunderbird < 128.12.
CVE-2025-6429 2 Mozilla, Redhat 8 Firefox, Firefox Esr, Enterprise Linux and 5 more 2025-11-03 6.5 Medium
Firefox could have incorrectly parsed a URL and rewritten it to the youtube.com domain when parsing the URL specified in an `embed` tag. This could have bypassed website security checks that restricted which domains users were allowed to embed. This vulnerability affects Firefox < 140, Firefox ESR < 128.12, Thunderbird < 140, and Thunderbird < 128.12.
CVE-2025-6425 2 Mozilla, Redhat 8 Firefox, Firefox Esr, Enterprise Linux and 5 more 2025-11-03 4.3 Medium
An attacker who enumerated resources from the WebCompat extension could have obtained a persistent UUID that identified the browser, and persisted between containers and normal/private browsing mode, but not profiles. This vulnerability affects Firefox < 140, Firefox ESR < 115.25, Firefox ESR < 128.12, Thunderbird < 140, and Thunderbird < 128.12.
CVE-2025-6424 2 Mozilla, Redhat 8 Firefox, Firefox Esr, Enterprise Linux and 5 more 2025-11-03 9.8 Critical
A use-after-free in FontFaceSet resulted in a potentially exploitable crash. This vulnerability affects Firefox < 140, Firefox ESR < 115.25, Firefox ESR < 128.12, Thunderbird < 140, and Thunderbird < 128.12.
CVE-2025-5986 2 Mozilla, Redhat 6 Thunderbird, Enterprise Linux, Rhel Aus and 3 more 2025-11-03 6.5 Medium
A crafted HTML email using mailbox:/// links can trigger automatic, unsolicited downloads of .pdf files to the user's desktop or home directory without prompting, even if auto-saving is disabled. This behavior can be abused to fill the disk with garbage data (e.g. using /dev/urandom on Linux) or to leak Windows credentials via SMB links when the email is viewed in HTML mode. While user interaction is required to download the .pdf file, visual obfuscation can conceal the download trigger. Viewing the email in HTML mode is enough to load external content. This vulnerability affects Thunderbird < 128.11.1 and Thunderbird < 139.0.2.
CVE-2025-5283 2 Google, Redhat 7 Chrome, Enterprise Linux, Rhel Aus and 4 more 2025-11-03 5.4 Medium
Use after free in libvpx in Google Chrome prior to 137.0.7151.55 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Medium)
CVE-2025-5269 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2025-11-03 8.1 High
Memory safety bug present in Firefox ESR 128.10, and Thunderbird 128.10. This bug showed evidence of memory corruption and we presume that with enough effort this could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 128.11 and Thunderbird < 128.11.
CVE-2025-5268 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2025-11-03 8.1 High
Memory safety bugs present in Firefox 138, Thunderbird 138, Firefox ESR 128.10, and Thunderbird 128.10. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 139, Firefox ESR < 128.11, Thunderbird < 139, and Thunderbird < 128.11.
CVE-2025-5267 2 Mozilla, Redhat 7 Firefox, Enterprise Linux, Rhel Aus and 4 more 2025-11-03 5.4 Medium
A clickjacking vulnerability could have been used to trick a user into leaking saved payment card details to a malicious page. This vulnerability affects Firefox < 139, Firefox ESR < 128.11, Thunderbird < 139, and Thunderbird < 128.11.
CVE-2025-5266 2 Mozilla, Redhat 7 Firefox, Enterprise Linux, Rhel Aus and 4 more 2025-11-03 4.3 Medium
Script elements loading cross-origin resources generated load and error events which leaked information enabling XS-Leaks attacks. This vulnerability affects Firefox < 139, Firefox ESR < 128.11, Thunderbird < 139, and Thunderbird < 128.11.
CVE-2025-5264 2 Mozilla, Redhat 7 Firefox, Enterprise Linux, Rhel Aus and 4 more 2025-11-03 4.8 Medium
Due to insufficient escaping of the newline character in the “Copy as cURL” feature, an attacker could trick a user into using this command, potentially leading to local code execution on the user's system. This vulnerability affects Firefox < 139, Firefox ESR < 115.24, Firefox ESR < 128.11, Thunderbird < 139, and Thunderbird < 128.11.
