net/mlx5e: fix a double-free in arfs_create_groups

published 2024-05-17 2 y ago modified 2026-08-05 3 mo ago also EUVD-2024-35748

cvss: 7.8; version 3.1, CNA
cisa kev: Not listed; not in CISA's catalog
epss: 0.6%; EPSS 0.6% chance of exploitation in 30 days, percentile 50%
public exploits: 0; none known

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

When `in` allocated by kvzalloc fails, arfs_create_groups will free ft->g and return an error. However, arfs_create_table, the only caller of arfs_create_groups, will hold this error and call to mlx5e_destroy_flow_table, in which the ft->g will be freed again.
