Vulnerability from github – Published: 2024-05-21 18:31 – Updated: 2024-11-07 18:31

Details

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

xfrm/compat: prevent potential spectre v1 gadget in xfrm_xlate32_attr()

int type = nla_type(nla);

if (type > XFRMA_MAX) { return -EOPNOTSUPP; }

@type is then used as an array index and can be used as a Spectre v1 gadget.

if (nla_len(nla) < compat_policy[type].len) {

array_index_nospec() can be used to prevent leaking content of kernel memory to malicious users.

Severity

2.5 (Low)
