"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nSquashfs: check metadata block offset is within range\n\nSyzkaller reports a \"general protection fault in squashfs_copy_data\"\n\nThis is ultimately caused by a corrupted index look-up table, which\nproduces a negative metadata block offset.\n\nThis is subsequently passed to squashfs_copy_data (via\nsquashfs_read_metadata) where the negative offset causes an out of bounds\naccess.\n\nThe fix is to check that the offset is within range in\nsquashfs_read_metadata. This will trap this and other cases."
