Echo: linux: security update to 6.12.57-1

low Tenable Cloud Security Plugin ID 457401

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: xen/events: Return -EEXIST for bound
 VIRQs Change find_virq() to return -EEXIST when a VIRQ is bound to a different CPU than the one passed in.
 With that, remove the BUG_ON() from bind_virq_to_irq() to propogate the error upwards. Some VIRQs are per-
 cpu, but others are per-domain or global. Those must be bound to CPU0 and can then migrate elsewhere. The
 lookup for per-domain and global will probably fail when migrated off CPU 0, especially when the current
 CPU is tracked. This now returns -EEXIST instead of BUG_ON(). A second call to bind a per-domain or global
 VIRQ is not expected, but make it non-fatal to avoid trying to look up the irq, since we don't know which
 per_cpu(virq_to_irq) it will be in. (CVE-2025-40160)

Solution

Update the linux library and its related packages to version 6.12.57-1 or later.
