A use-after-free flaw was found in concurrent DPC and hot-removal in the Linux kernel. This issue may result in a crash...

kernel: bpf: devmap: provide rxq after redirect

In the Linux kernel, the following vulnerability has been resolved: bpf: devmap: provide rxq after redirect rxq contains a pointer to the device from where the redirect happened. Currently, the BPF program that was executed after a redirect via BPFMAPTYPEDEVMAP does not have it set. This is...

kernel: vsock: prevent null-ptr-deref in vsock_*[has_data|has_space]

In the Linux kernel, the following vulnerability has been resolved: vsock: prevent null-ptr-deref in vsockhasdata|hasspace Recent reports have shown how we sometimes call vsockhasdata when a vsock socket has been de-assigned from a transport see attached links, but we shouldn't. Previous commits...

kernel: sunrpc: clear XPRT_SOCK_UPD_TIMEOUT when reset transport

In the Linux kernel, the following vulnerability has been resolved: sunrpc: clear XPRTSOCKUPDTIMEOUT when reset transport Since transport-sock has been set to NULL during reset transport, XPRTSOCKUPDTIMEOUT also needs to be cleared. Otherwise, the xstcpsetsockettimeouts may be triggered in...
