In the Linux kernel, the following vulnerability has been resolved:

sctp: fix memory leak in sctp_stream_outq_migrate()

When sctp_stream_outq_migrate() is called to release stream out resources, the memory pointed to by prio_head in stream out is not released.

The memory leak information is as follows: unreferenced object 0xffff88801fe79f80 (size 64): comm "sctp_repo", pid 7957, jiffies 4294951704 (age 36.480s) hex dump (first 32 bytes): 80 9f e7 1f 80 88 ff ff 80 9f e7 1f 80 88 ff ff ................ 90 9f e7 1f 80 88 ff ff 90 9f e7 1f 80 88 ff ff ................ backtrace: [] kmalloc_trace+0x26/0x60 [] sctp_sched_prio_set+0x4cc/0x770 [] sctp_stream_init_ext+0xd2/0x1b0 [] sctp_sendmsg_to_asoc+0x1614/0x1a30 [] sctp_sendmsg+0xda1/0x1ef0 [] inet_sendmsg+0x9d/0xe0 [] sock_sendmsg+0xd3/0x120 [] __sys_sendto+0x23a/0x340 [] __x64_sys_sendto+0xe1/0x1b0 [] do_syscall_64+0x39/0xb0 [] entry_SYSCALL_64_after_hwframe+0x63/0xcd
