Description
In the Linux kernel, the following vulnerability has been resolved:
tcp: Fix use-after-free of nreq in reqsk_timer_handler().
The cited commit replaced inet_csk_reqsk_queue_drop_and_put() with
__inet_csk_reqsk_queue_drop() and reqsk_put() in reqsk_timer_handler().
Then, oreq should be passed to reqsk_put() instead of req; otherwise
use-after-free of nreq could happen when reqsk is migrated but the
retry attempt failed (e.g. due to timeout).
Let's pass oreq to reqsk_put().
Affected configurations
• linux linux kernel (>= 5.15.170 < 5.15.174)
• linux linux kernel (>= 6.1.115 < 6.1.120)
• linux linux kernel (>= 6.6.59 < 6.6.64)
• linux linux kernel (>= 6.11.6 < 6.11.11)
• linux linux kernel (>= 6.12 < 6.12.2)
