What is CVE-2022-50206?

A concurrency vulnerability exists in the Linux kernel that can lead to a NULL pointer dereference, potentially resulting in a system crash. This issue arises when the emulation_proc_handler() function modifies the table->data simultaneously from multiple threads, causing unexpected behavior. To mitigate this vulnerability, it's crucial to implement proper mutex protection during updates to the current_mode and ensure stable access to the insn_emulation data. Users and administrators should remain vigilant and apply necessary updates to safeguard their systems.
