| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.48
Description
A null pointer dereference issue has been identified in the Linux kernel, specifically in the
cx23885 vdev init() function. This function can return a NULL pointer, which is then used without a check, potentially leading to a system crash. Local attackers may exploit this issue to crash the system.Recommendations
For Linux kernel versions prior to 6.6.48, upgrade the kernel to a version that includes the fix for this issue, such as version 6.6.48 or later. As a temporary workaround, consider adding a NULL pointer check in the
cx23885 vdev init() function to prevent the null pointer dereference.Exploit
