Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Fix inversion dependency warning while enabling IPsec tunnel
Attempt to enable IPsec packet offload in tunnel mode in debug kernel generates the following kernel panic, which is happening due to two issues: 1. In SA add section, the should be _bh() variant when marking SA mode. 2. There is not needed flush_workqueue in SA delete routine. It is not needed as at this stage as it is removed from SADB and the running work will be canceled later in SA free.
