CVE-2024-40991 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: dmaengine: ti: k3-udma-glue: Fix of_k3_udma_glue_parse_chn_by_id() The of_k3_udma_glue_parse_chn_by_id() helper function erroneously invokes "of_node_put()" on the "udmax_np" device-node passed to it, without having incremented its reference count at any point. Fix it.. EPSS estimates a 0.23% chance of exploitation in the next 30 days.
