CVE-2023-52828 bpf: Detect IP == ksym.end as part of BPF program

In the Linux kernel, the following vulnerability has been resolved: bpf: Detect IP == ksym.end as part of BPF program Now that bpfthrow kfunc is the first such call instruction that has noreturn semantics within the verifier, this also kicks in dead code elimination in unprecedented ways. For one...

CVE-2023-52828

CVE-2023-52828 (Linux kernel) : The vulnerability arises from BPF verifier handling after a bpf_throw call. Because bpf_throw is the first noreturn call in the verifier, dead code elimination causes subsequent instructions to be treated as unseen, which can affect stack unwinding when a program t...

CVE-2023-52735

The CVE-2023-52735 entry concerns a Linux kernel vulnerability in bpf/sockmap where sock_map_{close,destroy,unhash} could call themselves, risking a recursive loop and potential stack overflow. The design should prevent sock_map proto callbacks from calling themselves; the fix breaks recursive ca...

CVE-2023-52735 bpf, sockmap: Don't let sock_map_{close,destroy,unhash} call itself

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Don't let sockmapclose,destroy,unhash call itself sockmap proto callbacks should never call themselves by design. Protect against bugs like 1 and break out of the recursive loop to avoid a stack overflow in favor of...
