In the Linux kernel, the following vulnerability has been resolved:
misc: ocxl: fix possible refcount leak in afu_ioctl()
eventfd_ctx_put need to be called to put the refcount that gotten by
eventfd_ctx_fdget when ocxl_irq_set_handler fails.
A flaw was found in the Linux kernel's misc: ocxl component. A local attacker with low privileges could exploit a reference count leak in the afu_ioctl() function. This flaw occurs when ocxl_irq_set_handler fails to call eventfd_ctx_put to release a reference count obtained by eventfd_ctx_fdget. This could lead to a denial of service (DoS) due to resource exhaustion.
