      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nsctp: fix a TOCTOU race in SCTP_CMD_TIMER_START\n\nThe SCTP_CMD_TIMER_START handler checks timer_pending() before calling\ntimer_reduce(). The timer can expire and detach between these operations,\ncausing timer_reduce() to rearm the timer without taking the association\nreference required for the newly armed timer.\n\nThe timer callback later unconditionally drops its association reference,\nwhich can leave the association reference count unbalanced and result in\nuse-after-free during association teardown.\n\nUse the return value of timer_reduce() to determine whether the timer was\nactually armed. Take the association reference only when timer_reduce()\nsuccessfully starts a new timer, closing the race between checking the\ntimer state and rearming it.\n\nThis issue was reported by Nico Yip (@_cyeaa_) working with TrendAI Zero\nDay Initiative.",
