CVE-2026-98795
In the Linux kernel, the following vulnerability has been resolved: net: sparx5: skip ptp deinit if init was skipped sparx5_ptp_init() returns early on the base lan969x variants because they do not have the SPX5_FEATURE_PTP flag. It also returns early when no "ptp" interrupt is described. Unbinding the driver then causes a NULL pointer dereference when cleaning up uninitialized tx_skbs queues: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000008 Call trace: skb_queue_purge_reason+0x68/0x120 (P) sparx5_ptp_deinit+0x64/0xc0 mchp_sparx5_remove+0x38/0x70 platform_remove+0x20/0x30 device_remove+0x4c/0x80 Before per-port tx_skbs were added, a NULL dereference would have happened when calling ptp_clock_unregister() on the never-registered PTP clocks. Fix by returning early in sparx5_ptp_deinit() if PTP is not used.

Affected products and versions
NVD has not supplied machine-readable vulnerable CPE product/version entries for this CVE. This is an information gap, not proof that no products are affected. Check the vendor advisory references below.
Remediation & validation
- Identify exposure by comparing the affected product and version ranges with your asset inventory, SBOM and externally exposed services.
- Review the linked vendor security advisory or patch notes. Upgrade to a vendor-confirmed fixed release; do not infer a fixed version from the CVE description.
- Until patched, consider restricting network access or disabling the affected feature where operationally safe. These are temporary controls, not a substitute for a vendor fix.
- Validate the remediation with a version check and vulnerability rescan, then retain change evidence.
No fixed version is displayed unless it is explicitly established by a vendor advisory. Follow the vendor's release notes for exact product and branch applicability.
