CVE-2025-68728

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ntfs3: fix uninit memory after failed mi_read in mi_format_new<br /> <br /> Fix a KMSAN un-init bug found by syzkaller.<br /> <br /> ntfs_get_bh() expects a buffer from sb_getblk(), that buffer may not be<br /> uptodate. We do not bring the buffer uptodate before setting it as<br /> uptodate. If the buffer were to not be uptodate, it could mean adding a<br /> buffer with un-init data to the mi record. Attempting to load that record<br /> will trigger KMSAN.<br /> <br /> Avoid this by setting the buffer as uptodate, if it’s not already, by<br /> overwriting it.
