CVE-2024-50298
CVSS v3.1
5.5
Medium
| 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 (affected versions not specified)
Description:
A vulnerability in the Linux kernel has been resolved, related to the allocation of vf state during PF probes. In the previous implementation, vf state is allocated memory only when VF is enabled. However,
net device ops::ndo set vf mac() may be called before VF is enabled to configure the MAC address of VF. If this is the case, enetc pf set vf mac() will access vf state, resulting in access to a null pointer. This issue can be triggered by setting the MAC address of VF using the ip link set command, such as ip link set eno0 vf 1 mac 00:0c:e7:66:77:89. The error log shows a NULL pointer dereference at virtual address 0000000000000004.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
