For the CVE-2024-26865 issue, the stable 5.15 branch code also involves
this issue. However, the patch of the mainline version cannot be used on
stable 5.15 branch. The commit 740ea3c4a0b2("tcp: Clean up kernel
listener' s reqsk in inet_twsk_purge()") is required to stop the timer.

Eric Dumazet (1):
  tcp: Fix NEW_SYN_RECV handling in inet_twsk_purge()

Kuniyuki Iwashima (1):
  tcp: Clean up kernel listener's reqsk in inet_twsk_purge()
