CVE-2023-52997

CVE-2023-52997 is a Linux kernel vulnerability affecting ipv4: ip_metrics_convert() where an attacker could exploit speculative execution to leak kernel memory content. The issue arises from using a value as an array index (type) without sufficient protection, allowing a spectre v1 gadget. The de...

CVE-2023-52992

CVE-2023-52992 affects the Linux kernel; the vulnerability exists in BPF’s send_signal_common path where a task with pid=1 can trigger a kernel panic (kernel: “Attempted to kill init!”). A fix was applied to skip pid=1 in bpf_send_signal_common(), preventing this panic. Impact is local, with pote...

CVE-2023-52934

CVE-2023-52934 refers to a Linux kernel MADV_COLLAPSE issue. A change in MADV_COLLAPSE handling of pmd lookups (replacing a !pmd_present check with pmd_none) aims to distinguish none-pmd cases from absent/bad-pmd cases to prevent misclassifying swap or other entries as huge-pmd mappings. The prov...
