CVE-2023-52583
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: fix deadlock or deadcode of misusing dget() The lock order is incorrect between denty and its parent, we should always make sure that the parent get the lock first. But since this deadcode is never used and the parent dir will always be set from the callers, let's just remove it.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisShared resources are accessed without correct locking, so concurrent operations interleave into inconsistent — and sometimes exploitable — states, or deadlock the service outright. These bugs are subtle and timing-dependent. The fix is correct, consistent locking or atomic operations around every shared resource.

Linux kernel >= 4.19.307, >= 5.4.269, >= 5.10.210, or >= 5.15.149 (Debian 10 requires kernel from backports or distribution upgrade to Debian 11/12)
- 1. Identify the current running Linux kernel version using 'uname -r' or 'cat /proc/version'
- 2. Check which distribution version is in use (e.g., 'cat /etc/os-release' for Debian)
- 3. For Debian 10 (Buster) users: Upgrade to a kernel version >= 5.15.149 from Debian backports or consider upgrading to Debian 11/12 which include fixed kernels
- 4. For other distributions: Update the kernel package to a version >= 4.19.307, >= 5.4.269, >= 5.10.210, or >= 5.15.149 depending on your base kernel branch
- 5. Reboot the system to load the new kernel
- 6. Verify the fix is applied by checking 'uname -r' matches a fixed version and confirming ceph module loads without lockup issues
