SUSE CVE-2023-52828

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-2021-47298

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Fix potential memory leak on unlikely error case If skblinearize is needed and fails we could leak a msg on the error handling. To fix ensure we kfree the msg block before returning error. Found during code review...
