"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndm-integrity: fix buffer overflow in inline mode with large tag size\n\nIn inline mode, dm_integrity_check and dm_integrity_inline_recheck\ncompute the checksum of each block into an on-stack buffer of\nHASH_MAX_DIGESTSIZE bytes. integrity_sector_checksum pads its result\nwith zeroes up to the tag size, so if the tag size is larger than\nHASH_MAX_DIGESTSIZE, the padding runs past the end of the buffer. With\nCONFIG_STACKPROTECTOR the kernel panics in dm_integrity_check on the\nfirst read.\n\nEnlarge both buffers to hold MAX_TAG_SIZE bytes, as commit b93b6643e9b5\n(\"dm integrity: fix a crash with unusually large tag size\") did for\nintegrity_metadata.\n\nNote that this is not a security bug because the buffer overflow can only\nbe triggered by root."
