kernel: bpf: Add sk_is_inet and IS_ICSK check in tls_sw_has_ctx_tx/rx

A flaw was found in the Linux kernel. A local user can exploit this vulnerability to trigger a Denial of Service DoS through a system crash. The issue occurs in the Berkeley Packet Filter BPF socket map subsystem, where the kernel incorrectly assumes that all monitored sockets are standard Intern...

kernel: vsock: Fix sk_error_queue memory leak

A flaw was found in the Linux kernel's Virtual Socket vsock implementation. When zero-copy data transfers are used, completion notifications placed on a socket's error queue are not cleared when the socket is closed. A local user can exploit this flaw to trigger an uncollected memory leak,...
