Published Nov 8, 2024CWE-401EPSS 0.18%

Overview

CVE-2024-50190 is a medium-severity vulnerability. It was published on November 8, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

ice: fix memleak in ice_init_tx_topology()

Fix leak of the FW blob (DDP pkg).

Make ice_cfg_tx_topo() const-correct, so ice_init_tx_topology() can avoid

copying whole FW blob. Copy just the topology section, and only when

needed. Reuse the buffer allocated for the read of the current topology.

This was found by kmemleak, with the following trace for each PF:

[<ffffffff8761044d>] kmemdup_noprof+0x1d/0x50

[<ffffffffc0a0a480>] ice_init_ddp_config+0x100/0x220 [ice]

[<ffffffffc0a0da7f>] ice_init_dev+0x6f/0x200 [ice]

[<ffffffffc0a0dc49>] ice_init+0x29/0x560 [ice]

[<ffffffffc0a10c1d>] ice_probe+0x21d/0x310 [ice]

Constify ice_cfg_tx_topo() @buf parameter.

This cascades further down to few more functions.

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.
