Detailsinfo

A vulnerability, which was classified as critical, was found in Linux Kernel up to 7.1.4/7.2-rc1. This affects some unknown functionality of the component libata-core. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on availability. The summary by CVE is:

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.

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2026-72031 since 08/09/2026. The exploitability is told to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available.

Upgrading to version 7.1.5 or 7.2-rc2 eliminates this vulnerability. Applying the patch 299739909c486bcea7445f5c3b066fdbc0d2df96/462775c620197adaabc983ce847e5b9878ff4cb0 is able to eliminate this problem.
