CVE-2026-72031: ata: libata-core: Add NOLPM quirk for PNY CS900 1TB SSD

Q: What is the severity of CVE-2026-72031?

The severity of CVE-2026-72031 is rated at 20.

Q: How does CVE-2026-72031 affect PNY CS900 1TB SSD?

CVE-2026-72031 causes the PNY CS900 1TB SSD to drop off the bus after entering Device-Initiated Slumber during idle.

Q: How do I fix CVE-2026-72031?

To fix CVE-2026-72031, apply the latest updates from the Linux kernel that implement the NOLPM quirk.

Q: Is CVE-2026-72031 specific to certain SSDs?

Yes, CVE-2026-72031 specifically affects the PNY CS900 1TB SSD with a Phison PS3111-S11 controller.

Q: What configuration is affected by CVE-2026-72031?

CVE-2026-72031 is affected by the default med_power_with_dipm power policy in the Linux kernel.

Published Aug 15, 2026

Updated

In the Linux kernel, the following vulnerability has been resolved:

ata: libata-core: Add NOLPM quirk for PNY CS900 1TB SSD

The PNY CS900 1TB SSD (Phison PS3111-S11, DRAM-less) drops off the bus after entering Device-Initiated Slumber during idle. With the default medpowerwithdipm policy the link goes down (SStatus 1 SControl 300) and does not recover, forcing the filesystem read-only. Forcing maxperformance 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.
