DSA-2026-244: Security Update for Dell Automation Platform for Multiple Third-Party Component Vulnerabilities

For customers who configure general Linux shell access on DAP-Server nodes or want to implement defense-in-depth measures, Dell recommends adding a filter to block dynamic loading of the affected kernel module.

1.    Disable Vulnerable Kernel Module Loading From the DAP-Server Linux shell as system admin, add the following filter to the system configuration:

#Restrict loading of the affected kernel module echo "install algif_aead /bin/false" | sudo tee /etc/modprobe.d/disable-algif-aead.conf

After applying the configuration, update module preferences: sudo depmod –a 

2.    Verification To verify the module is blocked:

#Check if the module is active lsmod | grep algif_aead

#If necessary, unload the module if it is currently loaded sudo modprobe -r algif_aead

#Attempt to load the module (should fail) sudo modprobe algif_aead

#Expected output: modprobe: ERROR: ../libkmod/libkmod-module.c:1047 command_do() Error running install command '/bin/false' for module algif_aead: retcode 1

Persistence

The configuration will persist across system reboots. No additional steps are required.
