In the Linux kernel, the following vulnerability has been resolved:
staging: fbtft: core: set smem_len before fb_deferred_io_init call
The fbtft_framebuffer_alloc() calls fb_deferred_io_init() before
initializing info->fix.smem_len. It is set to zero by the
framebuffer_alloc() function. It will trigger a WARN_ON() at the
start of fb_deferred_io_init() and the function will not do anything.

kernel: staging: fbtft: core: set smem_len before fb_deferred_io_init call
In the Linux kernel, the following vulnerability has been resolved:
staging: fbtft: core: set smem_len before fb_deferred_io_init call
The fbtft_framebuffer_alloc() calls fb_deferred_io_init() before
initializing info->fix.smem_len. It is set to zero by the
framebuffer_alloc() function. It will trigger a WARN_ON() at the
start of fb_deferred_io_init() and the function will not do anything.
A flaw was found in the fbtft module in the Linux kernel. An incorrect order of operations can cause an improper initialization of framebuffer devices, potentially impacting system stability and resulting in a denial of service.
Statement: This issue has been fixed in Red Hat Enterprise Linux 8.8 via RHSA-2023:2951 [1].
