CVE-2022-3106

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.16-rc6

Description The issue is related to the ef100 update stats function in the drivers/net/ethernet/sfc/ef100 nic.c module of the Linux kernel, which lacks a check of the return value of kmalloc(). This can lead to a pointer dereference error. Exploitation of this issue may allow an attacker to cause a denial of service or elevate their privileges.

Recommendations For Linux kernel versions prior to 5.16-rc6, consider disabling the ef100 update stats function as a temporary workaround until a patch is available. Restrict access to the vulnerable module ef100 nic.c to minimize the risk of exploitation. Avoid using the kmalloc() function in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
