CVE-2024-26597

CVSS v2.0

10

High

VectorAV:N/AC:L/Au:N/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.1.0
Description The vulnerability is related to a global out-of-bounds read in the rmnet policy variable when parsing netlink attributes. This occurs because the rmnet link ops variable assigns a larger maxtype value, leading to an out-of-bounds read. The issue is detected by the KASAN (Kernel Address Sanitizer) tool. The vulnerability can be exploited to impact the confidentiality, integrity, and availability of protected information.
Recommendations To resolve the issue, update the Linux kernel to a version that includes the fix for the global out-of-bounds read in rmnet policy. Specifically, update to a version later than 6.1.0. As a temporary workaround, consider disabling the nla parse nested deprecated function until a patch is available. However, this may have unintended consequences and should be carefully evaluated before implementation.
