"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nice: fix locking for Tx timestamp tracking flush\n\nCommit 4dd0d5c33c3e (\"ice: add lock around Tx timestamp tracker flush\")\nadded a lock around the Tx timestamp tracker flow which is used to\ncleanup any left over SKBs and prepare for device removal.\n\nThis lock is problematic because it is being held around a call to\nice_clear_phy_tstamp.
