CVE-2022-50059
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn 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.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped5.10.1385.15.635.19.4
5.10.138 (for 5.10.x), 5.15.63 (for 5.15.x), or 5.19.4 (for 5.16-5.18.x)
- Identify the currently running Linux kernel version using `uname -r`
- Based on the current kernel version, determine the appropriate upgrade target: For 5.10.x branch, upgrade to >= 5.10.138; For 5.15.x branch, upgrade to >= 5.15.63; For 5.16.x-5.18.x branch, upgrade to >= 5.19.4
- Apply the distribution-specific kernel upgrade method (e.g., `apt-get dist-upgrade`, `yum update`, or rebuild from source with the specific version)
- Reboot the system into the new kernel
- Verify the fix is applied by checking the kernel version and confirming the commit 58dd4385577ed7969b80cdc9e2a31575aba6c712 is included
