What to Know

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

ksmbd: fix sd_ndr.data memory leak in ksmbd_vfs_set_sd_xattr

ndr_encode_v4_ntacl() allocates sd_ndr.data via kzalloc() at entry.

If any subsequent ndr_write_*() call returns error during encoding,

the allocated sd_ndr.data won't be freed and causes memory leak.

Move kfree(sd_ndr.data) into out label to ensure the buffer gets

released on all success and error return paths. (NVD)

What to Do

Monitor Linux's web page for any future patch releases.
