CVE-2025-40175 - idpf: cleanup remaining SKBs in PTP flows

CVE ID : CVE-2025-40175 Published : Nov. 12, 2025, 11:15 a.m. | 1 hour, 30 minutes ago Description : In the Linux kernel, the following vulnerability has been resolved: idpf: cleanup remaining SKBs in PTP flows When the driver requests Tx timestamp value, one of the first steps is to clone SKB using skb_get. It increases the reference counter for that SKB to prevent unexpected freeing by another component. However, there may be a case where the index is requested, SKB is assigned and never consumed by PTP flows - for example due to reset during running PTP apps. Add a check in release timestamping function to verify if the SKB assigned to Tx timestamp latch was freed, and release remaining SKBs.
