Hi,
The following vulnerability was published for amd64-microcode.
CVE-2025-62626[0]:
| RDSEED Failure on AMD Zen 5 Processors
Filling mainly for visibility, the same argumets we have for the other
pending amd64-microcode updates to not be able to update, at least [1]
mentions that a future update might include a fix, FWIW.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.

Changes:
amd64-microcode (3.20251202.1) unstable; urgency=medium
.
* Update package data from linux-firmware 20251202
* ATTENTION: regression risk if backported to stable or LTS.
The amd processor microcode updates in this release will not load on
systems with outdated BIOS vulnerable to "Entrysign" unless a number of
kernel patches are present.
* amd-tee: update AMD PMF TA Firmware to v3.1.
* amd-ucode: update with release 2025-12-02:
+ SECURITY UPDATE (AMD-SB-7055 / CVE-2025-62626)
Fix RDSEED Failure on more AMD Zen 5 Processor models
(closes: #1120005)
* amd-ucode: update with release 2025-11-13:
+ SECURITY UPDATE (AMD-SB-7055 / CVE-2025-62626)
Fix RDSEED Failure on more AMD Zen 5 Processor models
* amd-ucode: update with release 2025-10-30:
+ SECURITY UPDATE (AMD-SB-7055 / CVE-2025-62626)
Fix RDSEED Failure on some AMD Zen 5 Processor models
+ amd-ucode: update with release 2025-10-27:
* This is the final microcode release for systems that have not
been updated to fix vulnerability AMD-SB-7033 "Entrysign").
* A kernel update is needed for the microcode driver to be able
to select the appropriate microcode updates for outdated system
firmware vulnerable to "Entrysign".
* On non-updated kernels, this will potentially *regress* the
microcode version on the running system back to the one in the
(outdated, unpatched-for-Entrysign) BIOS.
+ amd-ucode: update with release 2025-07-29:
+ SECURITY UPDATE (AMD-SB-7029: CVE-2024-36350, CVE-2024-36357):
Mitigate transient execution vulnerabilities in some AMD processors
which might allow an attacker to infer data from previous stores
(TSA-SQ) or data in the L1D cache (TSA-L1), potentially resulting in
the leakage of privileged information and sensitive information across
priviledged boundaries (closes: #1109035)
* NOTE: Requires kernel and hypervisor changes for the security
mitigations to be applied (issue VERW instruction at appropriate
times).
* initramfs: guard against copying non-microcode data into the
early-initramfs bundle, for the benefit of those that copy all files from
linux-firmware into /lib/firmware/*. Thanks to Eric Valette for tracking
it down (closes: #1101350)
* debian/control: recommend cpio (closes: #1110987)
* NEWS.Debian: update for post-Entrysign microcode updates
Document that kernel patches are needed to avoid regressing the microcode
release on vulnerable Zen2/3/4 systems (family 0x19), and also that these
systems will not receive any future microcode updates.
