CVE-2023-53671

The CVE-2023-53671 issue affects the Linux kernel and is tied to SRCU behavior: when using SRCU_SIZE_SMALL, code assumed CPU 0 is always online. If a different CPU is the boot CPU (e.g., kdump with maxcpus=1), the system can hang, as observed on PowerPC where long task hangs were reported. The ro...

CVE-2023-53660

The CVE describes a Linux kernel issue in the bpf/cpumap path where ptr_ring cleanup does not correctly handle skb-mode SKBs as XDP frames, causing incorrect memory-type usage warnings when xdp_redirect_cpu runs with skb-mode and stress-mode. The root cause, per the Astra Linux advisory, is twofo...

CVE-2023-53656

The CVE-2023-53656 issue affects the Linux kernel perf path (drivers/perf: hisi) where a migration of the perf context to the CPU going to teardown can occur because cpu_online_mask() has not yet updated during cpuhp teardown. The result is a call trace (example: __switch_to, __schedule, mutex_lo...
