Dangling sk pointer in AF_SMC

CVE-2024-50293

What is CVE-2024-50293?

A vulnerability has been identified in the Linux kernel, specifically within the socket creation process, which could leave a dangling pointer if the socket creation fails. This issue arises during the handling of the SMC (Socket Memory Control) protocol, where the function responsible for creating sockets does not sufficiently clear the socket structure in the event of a failure. This oversight was highlighted in a kernel commit that aimed to enhance the safety of socket operations. Users and system administrators are encouraged to update their kernel versions to mitigate potential risks associated with this vulnerability.
