CVE-2017-1000253 3 Centos, Linux, Redhat 8 Centos, Linux Kernel, Enterprise Linux and 5 more 2026-04-21 7.8 High
Linux distributions that have not patched their long-term kernels with https://git.kernel.org/linus/a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (committed on April 14, 2015). This kernel vulnerability was fixed in April 2015 by commit a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (backported to Linux 3.10.77 in May 2015), but it was not recognized as a security threat. With CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE enabled, and a normal top-down address allocation strategy, load_elf_binary() will attempt to map a PIE binary into an address range immediately below mm->mmap_base. Unfortunately, load_elf_ binary() does not take account of the need to allocate sufficient space for the entire binary which means that, while the first PT_LOAD segment is mapped below mm->mmap_base, the subsequent PT_LOAD segment(s) end up being mapped above mm->mmap_base into the are that is supposed to be the "gap" between the stack and the binary.
CVE-2025-0239 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-21 4 Medium
When using Alt-Svc, ALPN did not properly validate certificates when the original server is redirecting to an insecure site. This vulnerability was fixed in Firefox 134, Firefox ESR 128.6, Thunderbird 134, and Thunderbird 128.6.
CVE-2025-1017 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-21 9.8 Critical
Memory safety bugs present in Firefox 134, Thunderbird 134, Firefox ESR 128.6, and Thunderbird 128.6. 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 was fixed in Firefox 135, Firefox ESR 128.7, Thunderbird 128.7, and Thunderbird 135.
CVE-2025-1930 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-20 8.8 High
On Windows, a compromised content process could use bad StreamData sent over AudioIPC to trigger a use-after-free in the Browser process. This could have led to a sandbox escape. This vulnerability was fixed in Firefox 136, Firefox ESR 115.21, Firefox ESR 128.8, Thunderbird 136, and Thunderbird 128.8.
CVE-2025-1931 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-20 7.5 High
It was possible to cause a use-after-free in the content process side of a WebTransport connection, leading to a potentially exploitable crash. This vulnerability was fixed in Firefox 136, Firefox ESR 115.21, Firefox ESR 128.8, Thunderbird 136, and Thunderbird 128.8.
CVE-2025-1932 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-20 8.1 High

CVE-2025-1933 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-20 7.6 High
On 64-bit CPUs, when the JIT compiles WASM i32 return values they can pick up bits from left over memory. This can potentially cause them to be treated as a different type. This vulnerability was fixed in Firefox 136, Firefox ESR 115.21, Firefox ESR 128.8, Thunderbird 136, and Thunderbird 128.8.
CVE-2025-1934 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-20 6.5 Medium
It was possible to interrupt the processing of a RegExp bailout and run additional JavaScript, potentially triggering garbage collection when the engine was not expecting it. This vulnerability was fixed in Firefox 136, Firefox ESR 128.8, Thunderbird 136, and Thunderbird 128.8.
CVE-2025-1937 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-20 7.5 High
Memory safety bugs present in Firefox 135, Thunderbird 135, Firefox ESR 115.20, Firefox ESR 128.7, and Thunderbird 128.7. 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 was fixed in Firefox 136, Firefox ESR 115.21, Firefox ESR 128.8, Thunderbird 136, and Thunderbird 128.8.
CVE-2025-9900 1 Redhat 10 Ai Inference Server, Discovery, Enterprise Linux and 7 more 2026-04-20 8.8 High
A flaw was found in Libtiff. This vulnerability is a "write-what-where" condition, triggered when the library processes a specially crafted TIFF image file. By providing an abnormally large image height value in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.
CVE-2025-2817 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-20 8.8 High
Thunderbird's update mechanism allowed a medium-integrity user process to interfere with the SYSTEM-level updater by manipulating the file-locking behavior. By injecting code into the user-privileged process, an attacker could bypass intended access controls, allowing SYSTEM-level file operations on paths controlled by a non-privileged user and enabling privilege escalation. This vulnerability was fixed in Firefox 138, Firefox ESR 128.10, Firefox ESR 115.23, Thunderbird 138, and Thunderbird 128.10.
CVE-2025-4091 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-20 8.1 High
Memory safety bugs present in Firefox 137, Thunderbird 137, Firefox ESR 128.9, and Thunderbird 128.9. 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 was fixed in Firefox 138, Firefox ESR 128.10, Thunderbird 138, and Thunderbird 128.10.
CVE-2025-5263 2 Mozilla, Redhat 7 Firefox, Enterprise Linux, Rhel Aus and 4 more 2026-04-20 4.3 Medium
Error handling for script execution was incorrectly isolated from web content, which could have allowed cross-origin leak attacks. This vulnerability was fixed in Firefox 139, Firefox ESR 115.24, 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 2026-04-20 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 was fixed in Firefox 139, Firefox ESR 115.24, Firefox ESR 128.11, Thunderbird 139, and Thunderbird 128.11.
CVE-2025-6424 2 Mozilla, Redhat 8 Firefox, Firefox Esr, Enterprise Linux and 5 more 2026-04-20 9.8 Critical
A use-after-free in FontFaceSet resulted in a potentially exploitable crash. This vulnerability was fixed in Firefox 140, Firefox ESR 115.25, 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 2026-04-20 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 was fixed in Firefox 140, Firefox ESR 128.12, Thunderbird 140, and Thunderbird 128.12.
CVE-2025-13601 2 Gnome, Redhat 41 Glib, Ceph Storage, Codeready Linux Builder and 38 more 2026-04-20 7.7 High
A heap-based buffer overflow problem was found in glib through an incorrect calculation of buffer size in the g_escape_uri_string() function. If the string to escape contains a very large number of unacceptable characters (which would need escaping), the calculation of the length of the escaped string could overflow, leading to a potential write off the end of the newly allocated string.
CVE-2025-0237 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-20 5.4 Medium
The WebChannel API, which is used to transport various information across processes, did not check the sending principal but rather accepted the principal being sent. This could have led to privilege escalation attacks. This vulnerability was fixed in Firefox 134, Firefox ESR 128.6, Thunderbird 134, and Thunderbird 128.6.
CVE-2025-0238 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-20 5.3 Medium
Assuming a controlled failed memory allocation, an attacker could have caused a use-after-free, leading to a potentially exploitable crash. This vulnerability was fixed in Firefox 134, Firefox ESR 128.6, Firefox ESR 115.19, Thunderbird 134, and Thunderbird 128.6.
CVE-2025-0240 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-20 4 Medium
Parsing a JavaScript module as JSON could, under some circumstances, cause cross-compartment access, which may result in a use-after-free. This vulnerability was fixed in Firefox 134, Firefox ESR 128.6, Thunderbird 134, and Thunderbird 128.6.
