In the Linux kernel, the following vulnerability has been resolved: net: enetc: avoid deadlock in enetctxonesteptstamp This lockdep splat says it better than I could: ================================ WARNING: inconsistent lock state 6.2.0-rc2-07010-ga9b9500ffaac-dirty 967 Not tainted...
CVE-2023-53022
CVE-2023-53022 concerns a deadlock in the Linux kernel’s enetc driver. The vulnerability stems from a locking sequence in enetc_tx_onestep_tstamp() where a work item runs in process context with softirqs enabled and holds netif_tx_lock. If a transmission interrupt occurs, the NET_TX softirq can r...

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...
