Echo: linux: security update to 6.1.159-1

high Tenable Self-Hosted Container Security Plugin ID 462665

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: bpf: Sync pending IRQ work before
 freeing ring buffer Fix a race where irq_work can be queued in bpf_ringbuf_commit() but the ring buffer is
 freed before the work executes. In the syzbot reproducer, a BPF program attached to sched_switch triggers
 bpf_ringbuf_commit(), queuing an irq_work. If the ring buffer is freed before this work executes, the
 irq_work thread may accesses freed memory. Calling `irq_work_sync(&rb->work)` ensures that all pending
 irq_work complete before freeing the buffer. (CVE-2025-40319)

Solution

Update the linux library and its related packages to version 6.1.159-1 or later.
