CVE-2025-22125
MediumSummary
W jądrze Linuxa zidentyfikowano podatność związaną z modułami md/raid1 i raid10, która polega na ignorowaniu flag IO. W przypadku włączonego domyślnie blk-wbt, wydajność zapisu w RAID jest znacznie obniżona z powodu throttlingu IO przez wbt dysków.
Risk Assessment
Organizacje mogą doświadczać znacznych spadków wydajności zapisu w systemach RAID, co może prowadzić do opóźnień w operacjach i obniżenia ogólnej efektywności systemu.
Recommendation
Zaleca się monitorowanie wydajności systemów RAID oraz rozważenie wyłączenia lub dostosowania ustawień blk-wbt, aby poprawić wydajność zapisu.

In node-opcua (an OPC UA implementation for TypeScript and Node.js), versions 2.42.0 through 2.180.0 do not honor namespace-level access control configured via setDefaultRolePermissions for nodes without explicit per-node permissions. SessionContext.getApplicableRolePermissions reads a missing or null value instead of the configured namespace field, and the null result is treated permissively. As a result, an anonymous network client can write variables or call bound methods when an operator relied on restrictive namespace defaults.

Original NVD description (English source)
In the Linux kernel, the following vulnerability has been resolved: md/raid1,raid10: don't ignore IO flags If blk-wbt is enabled by default, it's found that raid write performance is quite bad because all IO are throttled by wbt of underlying disks, due to flag REQ_IDLE is ignored. And turns out t
