CVE-2023-53121

The CVE-2023-53121 vulnerability affects the Linux kernel where tcp_rtx_synack() can be invoked from process context, allowing tcp_make_synack() to touch per-CPU data with preemption enabled and trigger a BUG: using __this_cpu_add() in preemptible code. The root cause is a context-inappropriate c...
