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: NFSD: fix race between nfsd
 registration and exports_proc As of now nfsd calls create_proc_exports_entry() at start of init_nfsd and
 cleanup by remove_proc_entry() at last of exit_nfsd. Which causes kernel OOPs if there is race between
 below 2 operations: (i) exportfs -r (ii) mount -t nfsd none /proc/fs/nfsd for 5.4 kernel ARM64: CPU 1:

 done & So exporting interfaces to user space shall be done at last and cleanup at first place. With change
 there is no Kernel OOPs. (CVE-2025-38232)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18244.582.11 or later.
