CVE-2026-99098

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> dm-integrity: fix buffer overflow in inline mode with large tag size<br /> <br /> In inline mode, dm_integrity_check and dm_integrity_inline_recheck<br /> compute the checksum of each block into an on-stack buffer of<br /> HASH_MAX_DIGESTSIZE bytes. integrity_sector_checksum pads its result<br /> with zeroes up to the tag size, so if the tag size is larger than<br /> HASH_MAX_DIGESTSIZE, the padding runs past the end of the buffer. With<br /> CONFIG_STACKPROTECTOR the kernel panics in dm_integrity_check on the<br /> first read.<br /> <br /> Enlarge both buffers to hold MAX_TAG_SIZE bytes, as commit b93b6643e9b5<br /> ("dm integrity: fix a crash with unusually large tag size") did for<br /> integrity_metadata.<br /> <br /> Note that this is not a security bug because the buffer overflow can only<br /> be triggered by root.
