Summary
In the Linux kernel, the following vulnerability has been resolved: smb/client: fix out-of-bounds read in symlink_data() Since smb2_check_message() returns success without length validation for the symlink error response, in symlink_data() it is possible for iov->iov_len to be smaller than sizeof(struct smb2_err_rsp). If the buffer only contains the base SMB2 header (64 bytes), accessing err->ErrorContextCount (at offset 66) or err->ByteCount later in symlink_data() will cause an out-of-bounds read.

CVE-2026-31613) OOB bytes are UTF-16-decoded into the symlink target and returned to userspace via readlink(2).\nI:N - The flaw is purely an out-of-bounds read of the error response buffer; it does not modify kernel memory.\nA:H - Reading past the message bounds can dereference invalid/unmapped memory and oops the client kernel, causing a denial of service."
