Linux Distros Unpatched Vulnerability : CVE-2025-4598

medium Nessus Plugin ID 247900

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - 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 more restricted data than unprivileged users or processes would be able to. An attacker can leverage this flaw by forcing a SUID process to crash and force the Linux kernel to recycle the process PID before systemd- coredump can analyze the /proc/pid/auxv file. If the attacker wins the race condition, they gain access to the original's SUID process coredump file. They can read sensitive content loaded into memory by the original binary, affecting data confidentiality. (CVE-2025-4598)

 - The systemd-coredump is prone to a kill-and-replace race condition which may allow a local attacker to gain sensitive information from crashed SUID processes. Additionally systemd-coredump does not specify %d (the kernel's per-process dumpable flag) in /proc/sys/kernel/core_pattern allowing a local attacker to crash root daemons that fork() and setuid() to the attacker's uid and consequently gain read access to the resulting core dumps and therefore to sensitive information from memory of the root daemons.
 (CVE-2025-4598)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
