published 2024-07-05 2 y ago modified 2026-06-17 4 mo ago also EUVD-2024-37998

cvss: 5.5; version 3.1, NVD
cisa kev: Not listed; not in CISA's catalog
epss: 0.2%; EPSS 0.2% chance of exploitation in 30 days, percentile 11%
public exploits: 0; none known

In the Linux kernel, the following vulnerability has been resolved:

If a process module does not have base config extension then the same format applies to all of it's inputs and the process->base_config_ext is NULL, causing NULL dereference when specifically crafted topology and sequences used.
