CVE-2024-50138
CVE-2024-50138 concerns the Linux kernel BPF ringbuf handling. The issue arises when __bpf_ringbuf_reserve is invoked from a tracepoint with preemption disabled, where using spinlock_t could trigger a “sleep in atomic” warning on RT variants. The root cause is the use of a spinlock_t in the ringb...

CVE-2024-50130
Summary: CVE-2024-50130 affects the Linux kernel, specifically the netfilter/bpf path. The issue arises when a BPF link is attached to a net namespace without taking a proper reference to the net namespace, allowing a use-after-free scenario during netns teardown. The bug manifests as a KASAN sla...
CVE-2024-50123
CVE-2024-50123 affects the Linux kernel sockmap/BPF code. The root cause is a missing BPF_LINK_TYPE invocation for the sockmap link, which caused an out-of-bounds read in bpf_link_show_fdinfo() for the sockmap link fd. The patch fixes the issue by adding the missing BPF_LINK_TYPE invocation and u...
