## Overview

In the Linux kernel, the following vulnerability has been resolved:

ceph: don't leak snap_rwsem in handle_cap_grant

When handle_cap_grant is called on an IMPORT op, then the snap_rwsem is
held and the function is expected to release it before returning. It
currently fails to do that in all cases which could lead to a deadlock.

## Affected

- `linux_kernel >= 5.8, < 5.10.138`
- `linux_kernel >= 5.11, < 5.15.63`
- `linux_kernel >= 5.16, < 5.19.4`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.19.4`
