ata: libata-core: Add NOLPM quirk for PNY CS900 1TB SSD
Published 2026-08-15 (2 months ago) by the Linux kernel CNA. Subsystem drivers/ata. Debian urgency: unimportant.
What to do, per Debian release
Debian's own status for CVE-2026-72031 in every release this site tracks, and what each one means in practice. Every status below is the one the Debian Security Team publishes for this CVE. source
| Release | Status | Version | What this means |
|---|---|---|---|
| Debian 12bookworm | not affected | 6.1.190-1 | Nothing to do. bookworm never shipped the vulnerable code. |
| Debian 13trixie | vulnerable | 6.12.113-1 | No fix published anywhere yet, neither in Debian nor upstream for the series trixie tracks. Watch the Debian tracker page for this CVE. Advisories for trixie have historically landed a median of 11 days after publication. |
| Debian 14forky | fixed | 7.1.5-1 | Update the kernel and reboot. Fixed in 7.1.5-1. A running kernel keeps the old code until the machine restarts. |
| Debian unstablesid | fixed | 7.1.5-1 | Update the kernel and reboot. Fixed in 7.1.5-1. A running kernel keeps the old code until the machine restarts. |
The vulnerability
What the bug is
The PNY CS900 1TB SSD (Phison PS3111-S11, DRAM-less) drops off the bus after entering Device-Initiated Slumber during idle. With the default med_power_with_dipm policy the link goes down (SStatus 1 SControl 300) and does not recover, forcing the filesystem read-only. Forcing max_performance keeps the link stable across prolonged idle. Add a NOLPM quirk so link power management is disabled for this drive specifically, leaving it intact for other devices on the host.
Where it lives
The fix touches these files. If the subsystem is one you do not use, the practical exposure is lower, though the package is still the vulnerable one.

Check it on the machine
grep -w CONFIG_ATA /boot/config-$(uname -r)Reads the booted kernel's own configuration, on the machine and nowhere else. =y is built in, =m is a module, and an is not set line means the code is not there.
lsmod | grep -w libataPrints a line if that module is loaded right now, and nothing if it is not. One that is not loaded can still be loaded later by anything that needs it.

Why the CNA scored it this way
The kernel CNA published no CVSS vector and no reasoning for CVE-2026-72031, which is why it is shown as unrated rather than given an invented score. 6,405 of the 20,413 CVEs here carry reasoning; this is not one of them.
