- Summary
- CVE-2026-46155 affecting package kernel for versions less than 6.6.141.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
smb/client: fix out-of-bounds read in smb2_compound_op()
If a server sends a truncated response but a large OutputBufferLength, and terminates the EA list early, check_wsl_eas() returns success without validating that the entire OutputBufferLength fits within iov_len.
Then smb2_compound_op() does: memcpy(idata->wsl.eas, data[0], size[0]);
Where size[0] is OutputBufferLength. If iov_len is smaller than size[0], memcpy can read beyond the end of the rsp_iov allocation and leak adjacent kernel heap memory.
