Lock Management Flaw in Linux Kernel's Nouveau Driver Affects GPU Performance

CVE-2024-56752

What is CVE-2024-56752?

The vulnerability within the Linux kernel's Nouveau driver involves an issue with mutex management that can arise during the execution of the gf100_gr_chan_new() function. Specifically, if the call to gf100_grctx_generate() fails, the necessary action of unlocking the mutex gr->fecs.mutex is not executed prior to return, which may lead to resource contention and potentially unstable GPU functionality. This flaw emphasizes the critical need for proper lock handling to ensure system stability and performance in graphical operations.
