CVE-2022-48819

Summary: CVE-2022-48819 affects the Linux kernel TCP path. When mixing sendpage() data and MSG_ZEROCOPY via the same socket, a warning in inet_sock_destruct() (sk_forward_alloc_get(sk)) could be triggered, due to the sendpage() path being forgotten in zerocopy handling and the need to keep zeroco...

SUSE CVE-2024-0646

An out-of-bounds memory write flaw was found in the Linux kernel's Transport Layer Security functionality in how a user calls a function splice with a ktls socket as the destination. This flaw allows a local user to crash or potentially escalate their privileges on the system...
