In the Linux kernel, the following vulnerability has been resolved:
ksmbd: validate zero numsubauth before subauth is accessed
Access psid->subauth[psid->numsubauth - 1] without checking if numsubauth is non-zero leads to an out-of-bounds read. This patch adds a validation step to ensure numsubauth != 0 before sub_auth is accessed.
