SUSE SLED15 / SLES15 / openSUSE 15 Security Update : grub2 (SUSE-SU-2025:01615-1)

medium Nessus Plugin ID 237073

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2025:01615-1 advisory.

 This update for grub2 rebuilds the existing package with the new 4k RSA secure boot key for IBM Power and Z.

 Note: the signing key of x86 / x86_64 and aarch64 architectures are unchanged.

 Also the following issue were fixed:

 - CVE-2025-4382: TPM auto-decryption data exposure (bsc#1242971)
 - Fix segmentation fault error in grub2-probe with target=hints_string (bsc#1235971) (bsc#1235958) (bsc#1239651)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
