Echo: linux: security update to 6.1.162-1

medium Tenable Cloud Security Plugin ID 460733

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: drm/vgem-fence: Fix potential deadlock
 on release A timer that expires a vgem fence automatically in 10 seconds is now released with
 timer_delete_sync() from fence->ops.release() called on last dma_fence_put(). In some scenarios, it can
 run in IRQ context, which is not safe unless TIMER_IRQSAFE is used. One potentially risky scenario was
 demonstrated in Intel DRM CI trybot, BAT run on machine bat-adlp-6, while working on new IGT subtests
 syncobj_timeline@stress-* as user space replacements of some problematic test cases of a dma-fence-chain
