medium Tenable Cloud Security Plugin ID 450452

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: iommu/amd/iommu_v2: Fix pasid_state
refcount dec hit 0 warning on pasid unbind When unbinding pasid - a race condition exists vs outstanding
page faults. To prevent this, the pasid_state object contains a refcount. * set to 1 on pasid bind *
incremented on each ppr notification start * decremented on each ppr notification done * decremented on
pasid unbind Since refcount_dec assumes that refcount will never reach 0: the current implementation
causes the following to be invoked on pasid unbind: REFCOUNT_WARN("decrement hit 0; leaking memory") Fix
this issue by changing refcount_dec to refcount_dec_and_test to explicitly handle refcount=1.
(CVE-2023-53501)
