CVE-2026-52948

A flaw was found in the Linux kernel's I2C Inter-Integrated Circuit subsystem. A malicious local user can exploit an integer overflow vulnerability in the I2CTIMEOUT ioctl. By providing a large timeout value, the multiplication by 10 causes an overflow, leading to a truncated value. This results ...

CVE-2026-52948

CVE-2026-52948 affects the Linux kernel I2C subsystem (i2c: dev) where the I2C_TIMEOUT ioctl accepts a user timeout in 10 ms steps. The argument is checked against INT_MAX but is then multiplied by 10 before passing to msecs_to_jiffies(). A malicious user can pass a value (e.g., 429496729) that p...
