3) NULL pointer dereference
EUVDB-ID: #VU87369
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-2024-26595
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the spectrum_acl_tcam() function in drivers/net/ethernet/mellanox/mlxsw/spectrum_acl_tcam.c. A local user can pass specially crafted data to the driver and perform a denial of service (DoS) attack.
