Description
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: DR, prevent potential error pointer dereference
The dr_domain_add_vport_cap() function generally returns NULL on error
but sometimes we want it to return ERR_PTR(-EBUSY) so the caller can
retry. The problem here is that "ret" can be either -EBUSY or -ENOMEM
and if it's and -ENOMEM then the error pointer is propogated back and
eventually dereferenced in dr_ste_v0_build_src_gvmi_qpn_tag().
Affected configurations
• linux linux kernel (>= 5.16 < 6.1.121)
• linux linux kernel (>= 6.2 < 6.6.67)
• linux linux kernel (>= 6.7 < 6.12.6)
• linux linux kernel 6.13
