A flaw was found in the Linux kernel's fbdev (framebuffer device) subsystem, specifically within the ssd1307fb driver. This vulnerability occurs when display damage callbacks, which handle updates to the display, perform synchronous I2C (Inter-Integrated Circuit) transfers from an atomic context. This can lead to a 'scheduling while atomic' bug, causing system instability or a denial of service (DoS) for a local user.
kernel: fbdev: ssd1307fb: defer I2C transfers from damage callbacks — rated Low by Red Hat. Released 2026-09-11, updated 2026-09-14.
