Overview

CVE-2022-48999 is a high-severity vulnerability. It was published on October 21, 2024 and has a CVSS 3.1 base score of 7.1 (HIGH).

Technical description

In the Linux kernel, the following vulnerability has been resolved:

ipv4: Handle attempt to delete multipath route when fib_info contains an nh reference

Gwangun Jung reported a slab-out-of-bounds access in fib_nh_match:

fib_nh_match+0xf98/0x1130 linux-6.0-rc7/net/ipv4/fib_semantics.c:961

fib_table_delete+0x5f3/0xa40 linux-6.0-rc7/net/ipv4/fib_trie.c:1753

inet_rtm_delroute+0x2b3/0x380 linux-6.0-rc7/net/ipv4/fib_frontend.c:874

Separate nexthop objects are mutually exclusive with the legacy

multipath spec. Fix fib_nh_match to return if the config for the

to be deleted route contains a multipath spec while the fib_info

is using a nexthop object.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
