CVE-2025-21788 (opens in a new tab)Amendment
The Centos security team deemed this advisory irrelevant for Centos:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-rt-debug-kvm package and not the kernel-rt-debug-kvm package as distributed by Centos.
In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: ti: am65-cpsw: fix memleak in certain XDP cases
If the XDP program doesn't result in XDP_PASS then we leak the memory allocated by am65_cpsw_build_skb().
It is pointless to allocate SKB memory before running the XDP program as we would be wasting CPU cycles for cases other than XDP_PASS. Move the SKB allocation after evaluating the XDP program result.
This fixes the memleak. A performance boost is seen for XDP_DROP test.
XDP_DROP test: Before: 460256 rx/s 0 err/s After: 784130 rx/s 0 err/s
