漏洞描述信息
在Linux内核中,已解决以下漏洞:
net/mlx5: DR, 修复mlx5_cmd_dr_create_fte中的滑块越界问题
当添加具有32个目的地的规则时,我们遇到以下非正常访问问题:
错误:KASAN:在mlx5_cmd_dr_create_fte+0x18ee/0x1e70处发生滑块越界
此补丁通过增加分配的缓冲区以容纳所需的操作,并通过检查操作的数量,防止提供操作过多的规则时发生此类问题,从而修复了此问题。

net/mlx5: DR, Fix slab-out-of-bounds in mlx5_cmd_dr_create_fte
漏洞描述信息
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: DR, Fix slab-out-of-bounds in mlx5_cmd_dr_create_fte
When adding a rule with 32 destinations, we hit the following out-of-band
access issue:
BUG: KASAN: slab-out-of-bounds in mlx5_cmd_dr_create_fte+0x18ee/0x1e70
This patch fixes the issue by both increasing the allocated buffers to
accommodate for the needed actions and by checking the number of actions
to prevent this issue when a rule with too many actions is provided.
