CVE-2026-1490
•
published on February 15, 2026
The Spam protection, Anti-Spam, FireWall by CleanTalk plugin for WordPress is vulnerable to unauthorized Arbitrary Plugin Installation due to an authorization bypass via reverse DNS (PTR record) spoofing on the 'checkWithoutToken' function in all versions up to, and including, 6.71. This makes it possible for unauthenticated attackers to install and activate arbitrary plugins which can be leveraged to achieve remote code execution if another vulnerable plugin is installed and activated. Note: This is only exploitable on sites with an invalid API key.

CVE-2026-23210
•
published on February 14, 2026
In the Linux kernel, the following vulnerability has been resolved:
ice: Fix PTP NULL pointer dereference during VSI rebuild
Fix race condition where PTP periodic work runs while VSI is being
rebuilt, accessing NULL vsi-rx_rings.
The sequence was:
1. ice_ptp_prepare_for_reset() cancels PTP work
2. ice_ptp_rebuild() immediately queues PTP work
3. VSI rebuild happens AFTER ice_ptp_rebuild()
4. PTP work runs and accesses NULL vsi->rx_rings
Fix: Keep PTP work cancelled during rebuild, only queue it after
VSI rebuild completes in ice_rebuild().
Added ice_ptp_queue_work() helper function to encapsulate the logic
for queuing PTP work, ensuring it's only queued when PTP is supported
and the state is ICE_PTP_READY.

CVE-2026-23210
•
published on February 14, 2026
In the Linux kernel, the following vulnerability has been resolved:
ice: Fix PTP NULL pointer dereference during VSI rebuild
Fix race condition where PTP periodic work runs while VSI is being
rebuilt, accessing NULL vsi-rx_rings.
The sequence was:
1. ice_ptp_prepare_for_reset() cancels PTP work
2. ice_ptp_rebuild() immediately queues PTP work
3. VSI rebuild happens AFTER ice_ptp_rebuild()
4. PTP work runs and accesses NULL vsi->rx_rings
Fix: Keep PTP work cancelled during rebuild, only queue it after
VSI rebuild completes in ice_rebuild().
Added ice_ptp_queue_work() helper function to encapsulate the logic
for queuing PTP work, ensuring it's only queued when PTP is supported
and the state is ICE_PTP_READY.
Error log:
[ 121.392544] ice 0000:60:00.1: PTP reset successful
