Echo: linux: security update to 6.1.180-1

high Tenable Cloud Security Plugin ID 459463

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: NTB: epf: Avoid calling
pci_irq_vector() from hardirq context ntb_epf_vec_isr() calls pci_irq_vector() in hardirq context to
derive the vector number. pci_irq_vector() calls msi_get_virq() that takes a mutex and can therefore
trigger "scheduling while atomic" splats: BUG: scheduling while atomic: kworker/u33:0/55/0x00010001 ...
Call trace: ... schedule+0x38/0x110 schedule_preempt_disabled+0x28/0x50
__mutex_lock.constprop.0+0x848/0x908 __mutex_lock_slowpath+0x18/0x30 mutex_lock+0x4c/0x60
msi_domain_get_virq+0xe8/0x138 pci_irq_vector+0x2c/0x60 ntb_epf_vec_isr+0x28/0x120 [ntb_hw_epf]
__handle_irq_event_percpu+0x70/0x3a8 handle_irq_event+0x48/0x100 handle_edge_irq+0x100/0x1c8 ... Cache the
Linux IRQ number for vector 0 when vectors are allocated and use it as a base in the ISR. Running the ISR
in a threaded IRQ handler would also avoid the problem, but that would be unnecessary here.
(CVE-2026-64430)

Solution

Update the linux library and its related packages to version 6.1.180-1 or later.
