Summary
[none]
Details

In the Linux kernel, the following vulnerability has been resolved: ksmbd: avoid out of bounds access in decodepreauthctxt() Confirm that the accessed pnegctxt->HashAlgorithms address sits within the SMB request boundary; deassemblenegcontexts() only checks that the eight byte smb2negcontext header + (client controlled) DataLength are within the packet boundary, which is insufficient. Checking for sizeof(struct smb2preauthnegcontext) is overkill given that the type currently assumes SMB311SALTSIZE bytes of trailing Salt.
