Jul 30 RESCORED — CVE-2025-21924 (Linux). CVSS 7.8 → 5.5 (NVD).
Description
In the Linux kernel, the following vulnerability has been resolved:
net: hns3: make sure ptp clock is unregister and freed if hclge_ptp_get_cycle returns an error
During the initialization of ptp, hclge_ptp_get_cycle might return an error

hclge_ptp_get_cycle failed.
