Описание

In the Linux kernel, the following vulnerability has been resolved: ksmbd: smbdirect: verify remaining_data_length respects max_fragmented_recv_size This is inspired by the check for data_offset + data_length.

A flaw was found in the Linux kernel's ksmbd component, specifically within the smbdirect module. This vulnerability occurs due to insufficient validation of the remaining_data_length against the max_fragmented_recv_size. A remote attacker could exploit this issue by sending a malformed network packet, which could lead to a denial of service (DoS) condition, making the system unresponsive.
