Description
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.
Affected configurations
• linux linux kernel (>= 5.18.3 < 5.18.18)
• linux linux kernel (>= 5.19 < 5.19.2)
