Echo: linux: security update to 6.1.147-1

medium Tenable Self-Hosted Container Security Plugin ID 462101

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: Initialize ssc before
 laundromat_work to prevent NULL dereference In nfs4_state_start_net(), laundromat_work may access nfsd_ssc
 through nfs4_laundromat -> nfsd4_ssc_expire_umount. If nfsd_ssc isn't initialized, this can cause NULL
 pointer dereference. Normally the delayed start of laundromat_work allows sufficient time for nfsd_ssc
 initialization to complete. However, when the kernel waits too long for userspace responses (e.g. in
 nfs4_state_start_net -> nfsd4_end_grace -> nfsd4_record_grace_done -> nfsd4_cld_grace_done ->
 cld_pipe_upcall -> __cld_pipe_upcall -> wait_for_completion path), the delayed work may start before
 nfsd_ssc initialization finishes. Fix this by moving nfsd_ssc initialization before starting
 laundromat_work. (CVE-2025-38231)

Solution

Update the linux library and its related packages to version 6.1.147-1 or later.
