medium Tenable Self-Hosted Container Security Plugin ID 463867

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: counter: interrupt-cnt: Drop
 IRQF_NO_THREAD flag An IRQ handler can either be IRQF_NO_THREAD or acquire spinlock_t, as
 CONFIG_PROVE_RAW_LOCK_NESTING warns: ============================= [ BUG: Invalid wait context ]

 alternative to switching to raw_spinlock_t, because the latter would limit all potential nested locks to
 raw_spinlock_t only. (CVE-2025-71180)

Update the linux library and its related packages to version 6.1.162-1 or later.
