| Vector | AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.3.2
Description
A use-after-free issue was found in the
dm1105 remove() function in the drivers/media/pci/dm1105/dm1105.c module of the Linux kernel. This issue is related to a race condition that allows for the reuse of previously freed memory due to concurrent access to a resource. Exploitation of this issue may allow an attacker to impact the confidentiality, integrity, and availability of protected information.Recommendations
For Linux kernel versions prior to 6.3.2, update to version 6.3.2 or later to resolve the issue. As a temporary workaround, consider disabling the
dm1105 remove() function until a patch is available. Restrict access to the vulnerable module drivers/media/pci/dm1105/dm1105.c to minimize the risk of exploitation.Fix
