Linux · Linux Kernel · CVE-2024-44944
**Name of the Vulnerable Software and Affected Versions**
Linux kernel versions prior to 6.6.50
**Description**
The issue is related to the netfilter's ctnetlink, where the delete expectation path is missing a call to the `nf expect get id()` helper function to calculate the expectation ID. This results in the leakage of the LSB of the expectation object address to userspace. An attacker could potentially exploit this to gain elevated privileges.
**Recommendations**
To resolve the issue, update the Linux kernel to version 6.6.50 or later. As a temporary workaround, consider restricting access to the vulnerable `ctnetlink` module to minimize the risk of exploitation.
