CWE-787

Description

In the Linux kernel, the following vulnerability has been resolved: ksmbd: prevent out-of-bounds stream writes by validating *pos ksmbd_vfs_stream_write() did not validate whether the write offset (*pos) was within the bounds of the existing stream data length (v_len). If *pos was greater than or equal to v_len, this could lead to an out-of-bounds memory write. This patch adds a check to ensure *pos is less than v_len before proceeding. If the condition fails, -EINVAL is returned.

Affected configurations

• linux linux kernel (>= 5.15 < 6.1.139) • linux linux kernel (>= 6.2 < 6.6.91) • linux linux kernel (>= 6.7 < 6.12.29) • linux linux kernel (>= 6.13 < 6.14.7) • linux linux kernel 6.15 • debian debian linux 11.0
