Описание
A flaw use after free in the Linux kernel video4linux driver was found in the way user triggers em28xx_usb_probe() for the Empia 28xx based TV cards. A local user could use this flaw to crash the system or potentially escalate their privileges on the system.
A use-after-free flaw was found in the Linux kernel’s video4linux driver in how a user triggers the em28xx_usb_probe() for the Empia 28xx-based TV cards. This flaw allows a local user to crash or potentially escalate their privileges on the system.
Меры по смягчению последствий
To mitigate this issue, prevent module em28xx from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically.
