CVE-2024-40996

CVE-2024-40996 affects the Linux kernel. Problem: bpf: Avoid splat in pskb_pull_reason where a debug WARN may trigger for SYZKALLER-style nets; not interesting for valid traffic and can be suppressed. Root cause involves a debug hint in pskb_may_pull when CONFIG_DEBUG_NET=y; with CONFIG_DEBUG_NET...

CVE-2024-40909

CVE-2024-40909 is a Linux kernel vulnerability resolved in the bpf subsystem. After commit 1a80dbcb2dba, a race could cause a use-after-free when bpf_link is freed by link->ops->dealloc_deferred but the code still tests and uses link->ops->dealloc afterward. The fix ensures only one o...
