An issue was discovered in ksmbd in the Linux kernel 5.15 through 5.19 before 5.19.2. There is an out-of-bounds read and OOPS for SMB2_WRITE, when there is a large length in the zero DataOffset case.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An issue was discovered in ksmbd in the Linux kernel 5.15 through 5.19 before 5.19.2. There is an out-of-     bounds read and OOPS for SMB2_WRITE, when there is a large length in the zero DataOffset case.
    (CVE-2022-47943)
