The Linux kernel's xfrm6_fill_dst function has a vulnerability that can lead to a double netdev_put issue. This occurs when the in6_dev_get(dev) function returns NULL, causing xfrm6_fill_dst() to release the device reference with netdev_put() but leave xdst->u.dst.dev set. Later, dst_destroy() calls netdev_put(dst->dev) again, resulting in the same net_device reference being released twice and underflowin [truncated]
A general protection fault occurs in the Linux kernel due to a vulnerability in the xfrm_hash_rebuild function. The function preallocates bins/chains for reinsertion, but its guard is inverted, causing it to skip policies with prefixlen < threshold and preallocate for the rest. This leads to a poisoned bydst node and a GPF on the next rebuild's hlist_del_rcu.
A slab-out-of-bounds read vulnerability was found in the Linux kernel's ksmbd module. The issue occurs when validating a compound SMB2 request, where the code reads the StructureSize2 field without checking if the compound element is large enough to contain it.
