| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
systemd versions 247 and later, with affected builds including those with libacl support
Description
A security flaw in systemd-coredump can cause a local information leak due to not respecting the fs.suid dumpable kernel setting. This issue allows an unprivileged local user to determine the contents of memory from privileged processes run with the suid root flag. The problem is present in the default configuration of various Linux distributions, including openSUSE, Arch, Debian, Fedora, and SLES.
Recommendations
For systemd versions 247 and later with libacl support, update to a version that includes the fix for this issue, as patches are already available on GitHub.
As a temporary workaround, consider restricting access to the vulnerable systemd-coredump component to minimize the risk of exploitation.
