Description

In the Linux kernel, the following vulnerability has been resolved: cifs: Fix memory and information leak in smb3_reconfigure() In smb3_reconfigure(), if smb3_sync_session_ctx_passwords() fails, the function returns immediately without freeing and erasing the newly allocated new_password and new_password2. This causes both a memory leak and a potential information leak. Fix this by calling kfree_sensitive() on both password buffers before returning in this error case.

Affected configurations

• linux linux kernel (>= 6.6.64 < 6.6.120) • linux linux kernel (>= 6.11.11 < 6.12) • linux linux kernel (>= 6.12.2 < 6.12.64) • linux linux kernel (>= 6.13 < 6.18.3) • linux linux kernel 6.19
