CVE-2025-6170 – Libxml2: stack buffer overflow in xmllint interactive shell command handling
https://notcve.org/view.php?id=CVE-2025-6170
16 Jun 2025 — A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful code in rare configurations without modern protections. Ahmed Lekssays discovered that libxml2 did not properly perform certain mathematical operations, leading to an integer overflow. An attacker could possibly use this issue to cause ... • https://access.redhat.com/security/cve/CVE-2025-6170 • CWE-121: Stack-based Buffer Overflow •

CVE-2025-49796 – Libxml: type confusion leads to denial of service (dos)
https://notcve.org/view.php?id=CVE-2025-49796
16 Jun 2025 — A vulnerability was found in libxml2. Processing certain sch:name elements from the input XML file can trigger a memory corruption issue. This flaw allows an attacker to craft a malicious XML input file that can lead libxml to crash, resulting in a denial of service or other possible undefined behavior due to sensitive data being corrupted in memory. Ahmed Lekssays discovered that libxml2 did not properly perform certain mathematical operations, leading to an integer overflow.

CVE-2025-4598 – Systemd-coredump: race condition that allows a local attacker to crash a suid program and gain read access to the resulting core dump
https://notcve.org/view.php?id=CVE-2025-4598
29 May 2025 — A vulnerability was found in systemd-coredump. This flaw allows an attacker to force a SUID process to crash and replace it with a non-SUID binary to access the original's privileged process coredump, allowing the attacker to read sensitive data, such as /etc/shadow content, loaded by the original process. A SUID binary or process has a special type of permission, which allows the process to run with the file owner's permissions, regardless of the user executing the binary. This allows the process to access... • https://access.redhat.com/security/cve/CVE-2025-4598 • CWE-364: Signal Handler Race Condition •

CVE-2025-5222 – Icu: stack buffer overflow in the srbroot::addtag function
https://notcve.org/view.php?id=CVE-2025-5222
27 May 2025 — A stack buffer overflow was found in Internationl components for unicode (ICU ). While running the genrb binary, the 'subtag' struct overflowed at the SRBRoot::addTag function. This issue may lead to memory corruption and local arbitrary code execution. A buffer overflow was discovered in the International Components for Unicode (ICU) library. For the stable distribution (bookworm), this problem has been fixed in version 72.1-3+deb12u1. • https://github.com/berkley4/icu-74-debian • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
