A security vulnerability exists in the Linux kernel that stems from the screeninfo module not properly relocating the frame buffer after a PCI bridge, which could lead to inval...

kernel: tty: Fix out-of-bound vmalloc access in imageblit

A vulnerability was found in the Linux kernel's tty subsystem within the imageblit function when a userspace program performs an ioctl operation with the FBIOPUTVSCREENINFO command, passing a fbvarscreeninfo structure with limited fields. If the structure’s values remain unchanged from a previous...
