About vulnerability

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 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.
