- CVE-2025-4598: Race condition that allows a local attacker to crash a SUID program and gain read access to the resulting core dump (bsc#1243935).
- CVE-2023-26604: Privilege escalation via the less pager (bsc#1208958).
- CVE-2022-4415: systemd-coredump was not respecting fs.suid_dumpable kernel setting (bsc#1205000).
Other bugfixes:
- clarify passno and noauto combination in /etc/fstab (bsc#1211725)
- handle -EINTR return from bus_poll() (bsc#1215241)
- /usr/ should never be unmounted regardless of HAVE_SPLIT_USR or not (bsc#1211576)

Описание
A vulnerability was found in systemd. This security flaw can cause a local information leak due to systemd-coredump not respecting the fs.suid_dumpable kernel setting.

Описание
systemd before 247 does not adequately block local privilege escalation for some Sudo configurations, e.g., plausible sudoers files in which the "systemctl status" command may be executed. Specifically, systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program. This presents a substantial security risk when running systemctl from Sudo, because less executes as root when the terminal size is too small to show the complete systemctl output.

Описание
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.
