In the Linux kernel, the following vulnerability has been resolved: bpf: Check the validity of nrwords in bpfiterbitsnew Check the validity of nrwords in bpfiterbitsnew. Without this check, when multiplication overflow occurs for nrbits e.g., when nrwords = 0x0400-0001, nrbits becomes 64, stack...

CVE-2024-53091

CVE-2024-53091 —The issue in the Linux kernel concerns TLS handling in sockmap with vsock and AF_UNIX sockets. The fix adds an IS_ICSK check to tls_sw_has_ctx_tx/rx because these socket types do not use inet_connection_sock, so tls_get_ctx could otherwise return an invalid pointer and trigger a p...
