Description

In the Linux kernel, the following vulnerability has been resolved: fbdev: imxfb: Check fb_add_videomode to prevent null-ptr-deref fb_add_videomode() can fail with -ENOMEM when its internal kmalloc() cannot allocate a struct fb_modelist. If that happens, the modelist stays empty but the driver continues to register. Add a check for its return value to prevent poteintial null-ptr-deref, which is similar to the commit 17186f1f90d3 ("fbdev: Fix do_register_framebuffer to prevent null-ptr-deref in fb_videomode_to_var").

• linux linux kernel (>= 3.11 < 5.4.297) • linux linux kernel (>= 5.5 < 5.10.241) • linux linux kernel (>= 5.11 < 5.15.190) • linux linux kernel (>= 5.16 < 6.1.148) • linux linux kernel (>= 6.2 < 6.6.102) • linux linux kernel (>= 6.7 < 6.12.42) • linux linux kernel (>= 6.13 < 6.15.10) • linux linux kernel (>= 6.16 < 6.16.1) • debian debian linux 11.0
