Crítica

VetorAV:N/AC:L/Au:N/C:C/I:N/A:C
Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.3.10
Description An issue in the Linux kernel's ksmbd module, specifically in fs/smb/server/smb2misc.c, does not validate the relationship between the command payload size and the RFC1002 length specification, leading to an out-of-bounds read. This could allow an attacker to access protected information or cause a denial of service.
Recommendations For Linux kernel versions prior to 6.3.10, update to version 6.3.10 or later to resolve the issue. As a temporary workaround, consider restricting access to the ksmbd module to minimize the risk of exploitation.
