CVE-2023-23006 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel before 5.15.13, drivers/net/ethernet/mellanox/mlx5/core/steering/dr_domain.c misinterprets the mlx5_get_uars_page return value (expects it to be NULL in the error case, whereas it is actually an error pointer).. EPSS estimates a 0.25% chance of exploitation in the next 30 days.
