Published: 2024-07-02 | Updated: 2025-05-13

Vulnerability identifier: #VU93612

Vulnerability risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2024-36007

CWE-ID: CWE-682

Exploitation vector: Local

Exploit availability: No

Vulnerable software:
Linux kernel
Operating systems & Components / Operating system

Vendor: Linux Foundation

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to incorrect calculation within the mlxsw_sp_acl_tcam_vregion_rehash_work(), mlxsw_sp_acl_tcam_rehash_ctx_vregion_changed(), mlxsw_sp_acl_tcam_vchunk_migrate_end(), mlxsw_sp_acl_tcam_vchunk_migrate_one(), mlxsw_sp_acl_tcam_vregion_migrate() and mlxsw_sp_acl_tcam_vregion_rehash_start() functions in drivers/net/ethernet/mellanox/mlxsw/spectrum_acl_tcam.c. A local user can perform a denial of service (DoS) attack.

Mitigation
Install update from vendor's website.
